Thermal energy refers to the kinetic energy of randomly moving particles in a substance. Particles can have translational, rotational, and/or vibrational kinetic energy, depending on the state of matter. Temperature is a measure of the average kinetic energy of the particles in a substance. Heat is thermal energy that transfers into or out of a system. Heat can transfer by conduction, convection, or radiation.

I love how you sound so enthusiastic! It makes learning this much more enjoyable

[@Aditya2364]

Thanks sir for this type of content❤. Very grateful to have access to your videos. Thanks again

[@123AndJC]

Thanks for making this, it is beneficial to research terms and gain a starting place to learn.
I have a question though.
Radiation = "no matter heat transfer". That appears factually not true, unless I am missing something.
Radiation: energy that moves from one place to another that can be described as waves or particles.
Please explain your definition.

Great job mr.mahesh 🎉
Plz continue the how i make khan academy videos series on floathead 🙏🙏

[@vikapavelitsa2393]

Thanks a lot! I would like to ask can I think about heat and thermal energy as the same things in terms of cooking?

[@Ibrahimkhattak17]

Thanks for teaching me for my science exam 🎉🎉🎉🎉🎉🎉🎉🎉❤❤❤❤❤❤❤😊😊😊😊😊😊

control of teh weak force vs the strong force withn the lectromatic feiold? how does gravity effect? the giggle or the back and forht?

best teacher

Why temperature isn't measured in joules as it is Average of kinetic energy of particles.

[@paromita_ghosh]

You know what you are talking about?? 🤣

[@Aditya2364]

​@@paromita_ghosh ? Can you please explain it to me

[@daisuu9747]

temperature is a measure itself.
