Calorimetry: Using q=mΔTc to find Temperature + Example

[@paulbuschman8318]

"If you didn't know water was one gram per milliliter, well then. you need to learn yourself something." HI - larious.

[@Nick-li8ol]

ty this 7min video helped me more than my 2hour long class U________U

[@The_Chosen_Heretic]

+nickOP I agree!

[@purplepanda7993]

agree

[@saulmunn3710]

same

[@peachypear8765]

for real 😭

[@chemistNATE]

Absolutely. You can carry units throughout the whole thing if you like. I find some students get lost when there are units floating around the linear equation though.

[@Im-me504]

dude you saved my life because my chemistry book was confusing the shit out of me with something so simple as this math equations you used.

[@froggyboi25]

Who else has finals tomorrow....? :)

[@jennahaor0244]

today >.

[@truedarkness4052]

Yep

[@shellyschwartz9908]

SAME

[@turtleboy440]

Me

[@eduardomenchaca1916]

Me tomorrow 😂

[@Palomino0813]

Once more, you've taken an equation that my textbook hopelessly overcomplicated and made it simple, and once more you have my thanks.

[@MizJustice]

The way this video just saved my life!! Thank you chemistNate!!!

[@christinamccarthy7659]

Cant thank you enough for doing this example. My prof made this question WAY more difficult than it needed to be and you simplified it making it painless and easy to solve. THANK YOU!!

[@lindsaykearney5089]

Haha I never realized how weird it is until now, but my chemistry teacher writes the formula as q=mc🔺t and she pronounces it like "q equals mcat" 😂

[@guardado56143]

Same with me, I find it easier to remember

[@arasa8896]

Lindsay Kearney onlar ne bilsin :D

[@sasamusic27]

haha wow that’s so funny man 😂

[@justynsc96]

9 equals mcat is a good mnemonic if you are studying for the MCAT exam, which requires you to know this equation ;)

[@MK_BABE]

lol

[@FHO72]

I love your videos. It's always so simple and straight forward. Thanks for making it easy for us struggling chemistry students. PS. MAKE MORE VIDEOS

[@victorialipps7061]

Because of you I will do great on my chem test! Thanks so much!!

[@Madpainter88]

SAVED MY LIFE! i have been trying to figure this out for ages and my text book is shit!. Sir, you earned yourself a sub! ily

[@ZeddsWorld]

thank you! this was way more helpful than my physics teachers lecture

[@dayneornelas296]

bless youuuuuuu!!! your "you need to learn something" comment made my night of chemheartache lol

[@clairetellkamp6253]

Bro, i love you. You're the only one I could find who answered this.

[@oskarkristinsson6517]

thank you i've been up for to long trying to find a good explanation you're a life saver.

[@Texman4268]

FANTASTIC. what a great explanation and thanks for breaking down the steps. Explained it a LOT better than my Physics guide did, that's for sure!!! Thanks again!!!

[@alonator09]

OMG, made sooo simple! thank you so so much! bless you

[@kaden56]

finally figured it out now that's it's 12:30 am thanks to your video! Thank you!

[@j0kokoh]

How would you solve an more complex problem involving 3 masses and 3 specific heat capacities asking for mass? e.g ice dropped in a glass of water

[@scottsibley561]

Did you ever find out how to complete these? I'd appreciate some resources on how these are done.

[@nickkoryukin4949]

At 2:12-2:15 did you mean 70mL or what you wrote??

[@whitneyxox4u]

you have no idea how much this just helped me!!! thank you tremendously !!!!

[@migbasketballer]

Thank you so much for posting this video! I have a test on this in two days and this helped me so much!!!! Thank you.

[@jackpodlasek9183]

i fucking love u @chemistNATE

[@ABWBackyardWrestling]

This helped so much you have no idea. Thank you so much!

[@Emily-xs8um]

OMG! Thank you so much! You helped me so much. I have been struggling with this concept for days!!!!!

[@megagodofwar23]

not being a troll or anything, but why did you use 70 grams if the problem had milliliters for water.

[@sliderulelover]

Very well presented. Kudos to your teaching technique. You also anticipated student's questions as you went along. Well done!

[@chr7688]

Thank you so much for this video. I've just spent 3 hours trying to solve a problem that you made simple in 6 minutes. Completely different than all the other examples out there but finally, logic I can understand!

[@The_Chosen_Heretic]

+ch r I've been spending roughly 6 hours on mine!

[@AndreaMercado13]

You are an amazing teacher!

[@jamesgibbons8855]

Very very helpful!!! Thank you so much for taking the time to do this!

[@rosemarydelgrosso8685]

I just wanted to say thank you so much for this video. My teacher gave the worst clues on how to solve a problem like this one so I am truly grateful to you.

[@mrswhiteschemistry4934]

Thanks for posting this. I found it helpful and will use it with my students.

[@4Yiger]

Thank you so much! I was so confused with my chem homework until I watched your video.

[@Jdop01]

10/10 Would solve again

[@aaronrapp4120]

BOOM! Nicely done best of luck

[@kaitlinj5887]

I understood this better in a 7 minute video than I did a two day lecture

[@natpat7683]

This was so helpful . I am forever grateful.

[@connorgoff3740]

This video was the only one that solved my question...thanks!

[@CrayEditz]

is the x in the answer the final temperature to the iron to the water?

[@stephens2663]

You're the man... I finally understand this!!! Thank you for making this!

[@sicilianotoronto]

Thank you! I tried this tonight but the Chem text was making the math so difficult to solve! You make it much easier!

[@chemistNATE]

Not that I'm aware of. Good question though.

[@koalasandfries]

this is awesome thank you Nate!! A way more simplified version to what I learned.

[@FranciscoGarcia-jy9rn]

thank you so much, I am reviewing for a final exam and this is helping me out.

[@normaeunicechavarria6191]

Thank you !!! I used this for a two part equation were the initial for the second part was the final for from my first part !!! Work out perfectly!!

[@sarahescamilla8417]

There is absolutely nothing simple about this. Why are 9th graders learning this??? They are so stressed out and so am I! I am in tears!!

[@chemistNATE]

9th grade !? This is done in Grade 12 Chemistry in Ontario, Canada Perhaps your Grade 9 teacher thinks it’s easy because “it’s just one formula” …

[@Manishh95]

love the videos, you'd be a great teacher sir

[@ellieb4306]

Why isn't the Ms 80g? I thought you're supposed to add both masses?

[@mrswhiteschemistry4934]

I'm just starting a youtube channel to help my students. I love your explanation. What do I tell them about dropping the units during the workup? Do they actually cancel out as it progresses?

[@katierobey-bhamani4435]

idk why but this hella made me laugh. but thanks I needed a memory refresher on this before my test tomorrow

[@flowerbased]

Is this the same as doing 2 seperate "q" formulas? I think this is how my teacher taught us for a constant calorimetry.

[@nascar12141]

Does it matter which - sign you put, either on iron or water? for q=-q... Either way result is the same, but is there any actual assignment of the negative sign?

[@insane204]

thank you so much for making this video and making it so simple ive been trying to learn this the whole day and with your video i can finally understand it thx a lot

[@lBankedlXboxGT]

insane204 hey its lBankedl the password is Raonguild I hope you find this

[@insane204]

thanks when I put to search ur guild It doesn't comes up can u write me exactly how u write ur alliance name to copy and paste

[@lBankedlXboxGT]

insane204 lBankedl YT

[@insane204]

I don't know why when I search ur guild It tells me somethings wrong I'll keep trying

[@lBankedlXboxGT]

lower case L uppercase B anked lowercase L Space uppercase YT

[@azizsaleh7508]

Thanks alot man, been around this equation for an hour ...

[@shindo567]

omg i have a test on this tomorrow! youre amazing haha, i know ill do better now

[@HanSoloxcs]

This just made a lot click for me. Thank you ChemistNate!

[@dasherman5150]

Good video. Thanks. I'd suggest dividing both sides of the linear equation by -4.6 as a second step though. It makes the numbers more manageable with only 'x-80' remaining on the right side.

[@melvinvasquez8518]

Thanks! CHEM 121 final tomorrow. This looks way harder in my textbook when you are casually glancing through; lol.

[@joycedjikeng4825]

are you Canadian???????

[@seanbyrnes6789]

This was extremely helpful!! Thank you very much!!

[@MaryBethUS]

Thank you!! Probably still going to fail my lab finals, but at least I'll get this problem correct.

[@BUFFYODAA]

Small world!

[@jakelennon8999]

Indeed...

[@luisambriz4673]

if you combined like terms why is there only one x in the end?

[@renrenx3328]

You made me love algebra! Thank you so much

[@macristinagalvez]

You’re awesome!!!! Please make more videos!

[@Chupabrah]

I think the REAL question here is are Maria, Romana and Andrea gonna tripple team this dudes beaker & show him the the practical aspect behind heat exchange between different bodies.

[@bruhhh6950]

So where did the 50 come from?

[@bodhi6481]

Thank you! SO much easier than I thought

[@LuisMartinez-rg5tr]

Thanks a ton. This was pretty helpful!

[@MsPichuMaster]

Finally someone who speaks English! Want to become my engineering buddy? hehe

[@Erikola18]

Thanks man you're a lifesaver!

[@williebangs1600]

Good job 👏 this video really helps

[@maddisonreeve2896]

How do you know what should be - and + for the initial plugging in of information? Is water endothermic?? Not quite sure what is going on with this part.

[@cristianacosta8656]

Why did the -4.6 turn positive when he moved it to the other side??

[@chelseaswan316]

Thank you so much!!!! This was so helpful to me!

[@imranwahabi3351]

helped me soo much bro thanks

[@iriscantrell]

Thanks so much! That was really helpful!

[@bethpadfield1633]

So helpful thank you!!!

[@45mcollins]

Lol you can hear a cop pulling someone over at 58 seconds

[@hmwhatsthisabout]

PLEASE MAKE A VIDEO ON ORGANIC CHEM EXAMPLE PROBLEMS

[@xtrol4330]

Jully and cellphone what the hell is going on 😡 I hate school

[@samfitzgerald7353]

Extremely helpful 🙏

[@KielyClan]

where does the 50 come from?

[@jrzrd411]

Wouldnt the units cancel? So you would have joules?

[@SquiggleWyrm]

How would you do this if there were three components? But two of them have the same change in temp. EX. 80 degree Copper dropped into 30 degree Celsius water held in 30 degree Celsius cup

[@yhelgacutan1558]

where'd you get 4.184 Sir?

[@sweethoodlove]

The heat capacity of water

[@pkralph3481]

Why can't I just find a professor like this in my school lol

[@SonicParkour6]

very helpful, thank you!

[@slg4567]

Literally just saved my life!!! yessss Thank youu

[@alexperez9180]

thanks for uploading, really helped alot

[@tomalley3585]

most people; ew algebra me; oh lemme get my lube and tissues. its 12 am and I have a physics exam in 7 hours..

[@christinamccarthy7659]

Do you have other examples of these types of Calorimetry problems? If so, can you direct me to the link? I would greatly appreciate viewing a few more of these.

[@pvp.ginger1473]

Where did u get the 0.46 j/gc from ????!

[@olliefearfield8346]

Google. It's just the accepted measurement for the Specific Heat Capacity of Iron, which is how much heat is needed to raise the temperature of 1 gram of a substance (iron) 1 degree Celsius

[@ameehasa5504]

Sir I have question I want to mixed one gallon water at 10 degree how much can I add hot water at 40 degree to get water at 30 degree ?

[@chattywattypatty]

Thank you so much! So helpful

[@Kimorawaytocuteforyou]

I am not understanding how you came up with the specific heat for iron. is that given??

[@Christian-Espinoza]

***** well you can solve for them, that is assuming that all other variables are given.

[@nike12385]

How do you know when to use negative and positive equations?

[@marlenealvarado9964]

You place the negative sign to the substance that is losing heat/energy. In this case the iron was "hotter" at 80degCelsius or had higher kinetic energy. Heat by definition is a form of energy that transfers from a system of higher kinetic energy to a system of lower kinetic energy. Consequently, in this example the iron lost the energy and the water absorbed this energy. Therefore, the negative sign indicates the substance that is losing energy.

[@johnmcnash9174]

Thank you so much this video was a life saver

[@corylatham3835]

Thank you! You explained this perfectly! :)

[@suffixable]

Why won't volume of water rise. Why is work done not looked?
