Solve: (a) (b) must be removed from the water to convert it to ice at (c) (d) Reflect: More energy is expelled to the room than is removed from the water. K is larger when is close to less energy must be expelled to move heat energy through a smaller temperature difference. 16.26. Set Up: For an isothermal process of an ideal gas, For an adiabatic process of an ideal gas, The Carnot cycle is sketched in Figure 16.11 in Chapter 16. Solve: and is positive. and is negative. For the adiabatic processes, and Dividing one equation by the other gives and This says so 16.27. Set Up: For an engine, W and are positive and is negative. For a refrigerator, is positive and W and are negative. A heat pump air conditioner takes in heat at a cool place and expels heat into a warm place. A heat pump house heater takes in heat at a cool place and expels heat into a warm place. For both types of heat pumps,
