There are a four kitchen pots on a hot stove and cuch one has the same volume of water. which one of the kettles below will bring the water to aboil temperature? at the highest (a) a tall and narrow pot that is covered with a heavy lid (b) a short and wide pot covered with a heavy lid (c) a tall and narrow pot that is uncovered (d) a short and wide pot that is uncovered (e) none of the above. they will all boil at the same temperature.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
