Expert Answer

Answer

None

Explanation

According to first law of thermodynamics

∆U = q + w

where

∆U = internal energy of system

q = heat released or absorbed by the system

w = work done by or done on system

From the first law of thermodynamics we know that ∆U is depends both on q and w but not resticted only to either q or w.
