Exercises: 1. A Carnot engine generates work from the spontaneous heat transfer from a 400°C heat source to a 25°C heat sink. If 100 J of heat was supplied to this engine, what would be the amount of work that can be extracted from it? 2. A Carnot refrigerator is set to maintain a temperature of 0°C for a system against the surroundings that is at 30°C by actively transferring 100J of heat from the system to the surroundings. What about of work must this refrigerator expend to maintain the temperature difference?

A cube of ice is taken from the freezer at -8.1°C and placed in a 91 g glass cup filled with 318 g of water. Both the water & the cup are at 23.3°C. Eventually the system reaches thermal equilibrium at 17.6°C. Determine Qcup, Qwater (for the water initially in the cup), Qice, & the mass of the ice. (note:use the images to find the specific heat and any additional information note conversion from grams to kilograms must be done) Qcup= Qwater= Qice= mass of ice=

Consider a piston (or box) pressurized with air. Suppose you compress the piston so that the final volume is half the starting volume but the temperature remains the same. For a reversible process, i) would the work done on the system be the same or change whether you modeled the gas ideal or real? ii) For an irreversible process, would the work done on the system be the same or change whether you modeled the gas as ideal or real assumng that you applied the same external force for compression? Explain your answer.
