11/12.1 Heat and Calorimetry | General Physics

[@jasonsias95]

Thank you for your passion for science and helping many get a better grasp of the material. You aided me in passing general physics 1 this fall. God bless you and happy holidays, Chad!

[@ChadsPrep]

To you as well! Glad to hear the channel helped - keep up the hard work!

[@pranavmuthukumaran9717]

Hey Chad. I am so grateful that I found you. I wanted to ask you something. Can you please make more full length lectures?

[@ChadsPrep]

Glad you're finding the videos beneficial! Can you give me a little more of an ideal of what you mean when you say "full length" videos?

[@dpete322]

Hey Chad. I just want to say thank you so much for your videos in gen gem, orgos. They really helped me a lot in my first year of study. ❤What are you planning to do in the next year? Biochem?

[@jbmu4644]

Excellent as always Chad!

[@ChadsPrep]

Thanks!

at 21:27, wouldn't the total heat be 291,900 J

[@Lking123]

Yes, that's what I got.

15:27 is the time in the video and it is about heat and calorimetry ok. Sir the question is that when we have a phase change in liquid water into a gas at 100 degree celceus T then sir the temperature of water doesn't change until all the water is converted into gas because you said that at phase change adding heat does not change the temperature of the substance it simply breaks the IMFs in water until all of it is converted into a gas? And the temperature of water remain 100 degree celceus until all of it is converted into gas?

[@ChadsPrep]

If you have gaseous and liquid water present together in a closed container in equilibrium, then as you boil the water, both the liquid and gaseous water will maintain a temperature of 100 degrees Celsius until all of the water is vaporized. But once all the water is in the gaseous phase, the addition of more heat will now cause a rise in the temperature of the gaseous water. Hope this helps!

[@SakeenaManzoor-u4y]

Sir well in open system it doesn't works because you specify only a close container?

[@thatboyss5576]

Chad are you at ABRCMS

[@ChadsPrep]

Is this a conference? In which case probably not :)
