The greatest difference between this channel and my teacher is that it doesn't try to cover the syllabus,instead it ACTUALLY HELPS.

[@Dcrvuhnuhbygg......]

I don't know where else to report this error: In a physics practise question on density it goes like this: "The density of sodium is 0.968 g/cm3. What is its density in kg/m3?" The two options are: "0.000968 kg/cm3 968 kg/cm3" And then it talks about dm cubed: "Not quite! To convert g/cm3 to kg/dm3 you have to convert" I think there is an error with either the answer or the question - maybe a typo. Hope this was helpful!

Thank you for the video, it’s really helpful. I just have a question: I don’t get how 1g/cm3 is equal to 1000kg/m3? I though that 1g is equal to 1000kg, so surely it should be the other way round?

[@duazia9737]

I'm afraid that you have a very serious misconception, my friend. 1 kilogram is equal to 1000 g, NOT the other way around. You can remember this by knowing that a person would be measured in kilograms (for example, I am 57 kg). Something like a mobile phone would be measured in grams. To measure me, you would need a LOT of mobile phones of mobile phones to equal my weight. (it's actually mass, but don't worry about that). Basically: A KILOGRAM IS A HUGE THING WHICH HAS A LOT (1000) SMALL GRAMS IN IT.

[@danielwright5657]

@@duazia9737 1000g = 1kg but there are 1,000,000 cm3 in 1m3. (1 metre = 100cm; so a 1m3 block has a volume 100cm x 100cm x 100cm = 1,000,000cm3) So 1g/cm3 is equal to 1000kg/m3 because 1m3 = 1,000,000cm3, and 1,000,000g=1,000kg.

divide mass by density

[@joshwestwood668]

Hi there, Please correct me if I’m wrong, but I believe your conversions in this video may be inaccurate. There are 100cm per 1m and there are 1000g per 1kg. If the solid aluminium has a density of 2710kg/m3, I believe the conversions would be as follows: To calculate grams, it would be 2710 x 1000 = 2710000g. Therefore, there would be 2710000g/m3. Then to find the number of grams per cm, it would be 2710000 / 100 = 27100g/cm3. This makes your conversion of 1g/cm3 = 1000kg/m3 inaccurate as: 1000kg = 1000000g. 1000000g / 100 = 10000g/cm3 Therefore, shouldn’t it be 10000g/cm3 = 1000kg/m3?

[@Cognitoedu]

Hi, not quite, to covert from g/m^3 to g/cm^3 you have to divide by 100 three times, because volume has 3 dimensions, so you’re dividing by 1,000,000 overall. You can try putting it into google and it will covert it for you :)

[@dangerousboy3887]

Hey, I have a quick question... What if you don't have an eureka can but a measuring cylinder? Can we measure the density of an irregular solid with that?

[@flower_chain7098]

Yes. You first pour in some water into the measuring cylinder. You then check how much it is (for example 20ml) then you add the irregular object. The difference between the initial volume and the volume after you added the object is the volume of your object. (For example, if after adding it it’s 26ml, then 26-20 is 6 and that’s your volume.)

How do you find the density of an irregular object denser than water and one lighter than water? Isnt it the same procedure? Need it for my summer hw :(

[@elecbqrr]

It’s the same as water will still be displaced

[@zahraabdulaleem4920]

if the density is lighter, you'll have to use multiple of the objects. For example paper clips, one is too light to see the measurement so you put ten of them in water and divide the water difference by 10. Idk if this makes sense lol

cm cubed is volume and ml is mass

[@lizxyplays5331]

I have a question in the first equation where we had to find the volume i got the answer on my calculator as 0.154 but in the video it was 0.155 , does that make a difference?

[@Pawan_013]

Your answer is wrong. He put his answer to 3 d.p( decimal place ). So , if i divide 420 by 2710 ( 420/2710 ) , the answer on calculator is 0.1549815498 You CANNOT just pick the 3 digits after the decimal place to make up the answer to 3 d.p. Let me give an example : Ex 1 ) 420/2710 , giving you answer to 3 decimal place. In calculator it's : 0.15498.... But we need only 3 digits after the decimal..., so , count 3 digits after the decimal and put a ( | ) after it , : 0.154 | 98... ~ Now check the number that is after the line that we drew ( | ) , if it it ( 0 - 4 ) , then your answer would be ( 0.154 ). ~ However if the number is between ( 5 - 9 ) , you need to add 1 to the previous digit... , as in this example , the number after the line is between 5 to 9 , we need to add 1 to the previous digit : Here : 0.15(4+1) = 0.155
