Question

200 joule of work is done on a gas to reduce its volume by compressing it. If this change is done under adiabatic conditions, find out the change in internal energy of the gas and also the amount of heat absorbed by the gas?

Answer 1

Answer:

In adiabatic changes, dQ = 0 From dQ = dU + dW = 0 dU = -dW = -(200 J) = 200 J Internal energy increases by 200 J. Heat absorbed is zero.
