Solution

The mathematical expression for the first law of thermodynamics is,
ΔU = q + w
When ΔU = change in energy
             q = heat absorbed by the system
             w = Amount of work done
Adiabatic Process : A process in which heat is not allowed to enter or leave the system at any stage the process is called adiabatic process.
∴ q = 0
The mathematical expression for first law of thermodynamics is,
ΔU = q + w
∴ ΔU = + w
