Question

Let Q and W denote the amount of heat given to an ideal gas and the work done by it in an adiabatic process.

Answer 1

Answer:

In an adiabatic process, no heat is supplied to the system; so, Q = 0. According to the first law of thermodynamics, heat given to any system is equal to the sum of the change in internal energy and the work done on the system. So, Q = W+U and as Q = 0, W = -U and Q ≠ W
