Electronic, vibrational and rotational transitions are all quantised. When molecules and atoms gain energy they exist in higher energy states whereby they can access the higher quantum states. As they collide with other molecules and atoms they can transfer some of that energy by going from a higher quantum state back to a lower quantum state. That difference in energy is equivalent to the increase in energy that is transferred, That transfer of energy is heat.

Can you please explain at the atom level what exactly is the process by which heat can get in or get out . I just find it so abstract when we say " heat get out from the system " : (
I'm just finding it so confusing because till now I don't know what's the process by which heat transfer from one system to another : (

So is it isothermal because an even amount of heat is absorbed and lost? In which case is it also diathermic? o.o
