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
