Temperature, Thermal Energy, and Heat - IB Physics

This video goes over the definitions of temperature, internal or thermal energy, and heat, and explains how each is different from the other and how all the definitions connect to the kinetic theory of matter. I explain how two objects with the same temperature can have different thermal energy, how cold objects can have more thermal energy than hot objects, temperature scales and units (Fahrenheit, Celsius, and Kelvin), absolute zero, heat transfer, and what the conservation of energy tells us about heat.

its been two years since the video was published and it is still so helpful to understand IB physics!!! keep up the good work 👍👍👍👍

I just wanna say thank you so much. You have been a really big help in getting me through IB physics

[alexfontaine]

This is an outstanding video you couldn’t have done a better job thanks a bunch

[cdpalmo]

thank you so much for this playlist prof, helps me a lot

potential energy is due elevation, or gravity. The internal energy from bonds is chemical energy, binding is the strong nuclear force and sensible energy is the forms kinetic of the molecules

thanks for sharing this valuable ppt. do you offer them for sale on any website?

[jad]

your explaining is better than my teachers 🤣🤣🤣😂😂😂😂😆😆😆😆

Thank you this is such a great video! I just have a question. For the definition of temperature, why do you have to say 'average kinetic energy per particle'? Because doesn't average encompass the 'per particle' bit as you showed in your calculation?

I believe there is an error with the table because Thermal Energy should be another term for Heat and NOT internal energy.

Please tell me good book for thermodynamics
