Q5. (20 marks) Fig. 1 displays a closed cycle for a gas. From B to C, 40 J is transferred to the gas as heat. From C to A, 130 J is transferred from the gas as heat, and the magnitude of the work done by the gas is 80 J. From A to B, 400 J is transferred to the gas as heat. a) Supply the plus and minus signs for the given data and explain. b) Compute the work done by the gas from A to B. B Fig. 1
