Write the first law of thermodynas law of thermodynamics for an adiabatic process.

W = - ΔE

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
