Question

Write mathematical equation of first law of thermodynamics for Adiabatic process

Solution

In an adiabatic process, there is no exchange of heat between the system and its surroundings, i.e. q = 0.

Therefore, the equation

triangle U=q+W

Becomes

triangle U=W or-triangle U=-W

The above equation indicates that the increase in internal energy of the system is due to the work done on it by the surroundings or that the work done by the system on the surroundings is at the expense of the system’s internal energy which decreases in the process.

Is there an error in this question or solution?
