VA = 0.95 × 10-3 m3VB = 3.5 × 10-3 m3PA = 2.65 × 106 N/m2PB = 2.37 × 106 N/m2PC = 0.75 × 106 N/m2PD = 1.29 × 106 N/m2 a)Calculate the net work output, in joules, of the heat engine following path ABCDA.The hot reservoir for a Carnot engine has a temperature of 938 K, while the cold reservoir has a temperature of 362 K. The heat input for this engine is 7110 J. The 362-K reservoir also serves as the hot reservoir for a second Carnot engine. This second engine uses the rejected heat of the first engine as input and extracts additional work from it. The rejected heat from the second engine goes into a reservoir that has a temperature of 213 K. Find the total work delivered by the two engines.What is the decrease in entropy of 44.8 g of water that condenses on a bathroom mirror at a temperature of 39.7°C, assuming no change in temperature and given the latent heat of vaporization to be 2450 kJ/kg?
