Answer:

W= - ΔE

Step-by-step explanation:

First law of thermodynamics :

This law is also known as energy conservation law.According to this law the total energy of isolated system will be constant.

From first law of thermodynamics

Q = W + ΔE

Q= Heat transfer

W=Total work ( Mechanical work ,Electrical work ....)

ΔE = Total energy (Kinetic energy, Internal energy ....)

As we know that in adiabatic process there no any heat transfer.It means that Q= 0

So for an adiabatic process

Q = W + ΔE

Q= 0

0= W + ΔE

W= - ΔE
