1.A Carnot air conditioner keeps the temperature in a house at 297 K on a day where the outside temperature is 311 K. What is the coefficient of performance of this air conditioner? 2.A Carnot engine has an efficiency of 22.0%. It is operating between two reserves at constant temperature that differ by 750C. What is the minimum temperature (TL) and the maximum temperature (TH)?

A window air conditioner uses 1307 W of electricity and has a coefficient of performance of 2.75. For simplicity, let's assume that all of that electrical energy is transformed into work done by the air conditioner to cool a room with dimensions of 7 m x 7 m x 3 m. The air inside this room will initially have the same temperature as the air outside (319 K) and the air conditioner will attempt to cool the room to 295...

A Carnot engine works between two heat reservoirs at temperatures Th = 360 K and Tc = 240 K. (a) What is its efficiency? % (b) If it absorbs 95 J from the hot reservoir during each cycle, how much work does it do? J (c) How much heat does it give off during each cycle? J (d) What is the COP of this engine when it works as a refrigerator between the same two reservoirs?

A heat pump operates between reservoirs at 299 K (inside the house) and 257 K (outside). It is not a reversible heat pump; it only pumps 74% of the maximum possible heat into the house. How much work must be done to “pump” 6500 J of heat energy into the house?
