उत्तर

Internal energy of a system increases if its temperature increases. This is valid only for the system of ideal gases and not for all the systems.

For example:- During meting process, temperature of the system remains constant, but internal energy change increases by mL.

⇒ ΔU = mL

Here,

m = Mass of the solid

L = Latent heat of the solid
