Whenever we add heat to the system, the KE of the particles increase and so does their momentum. Thus every time we heat an object by any means, we change the momentum of the particles or in other words, we do work on them.
How do heat and work affect a system?
=
Heat and work are two different ways of transferring energy from one system to another. ... The first law of thermodynamics states that heat and work both contribute to the total internal energy of a system, but the second law of thermodynamics limits the amount of heat that can be turned into work.
What happens when heat is added to the system?
=
If heat is added to the system its internal energy will increase; if heat is removed from the system its internal energy will decrease.
