Plzzz ! what is the main difference between a permanent magnet and a temporary magnet? a permanent magnet is made of a ferromagnetic material, while a temporary magnet is not. a temporary magnet attracts only metal objects, while permanent magnets attract both metal objects and other magnets. the domains in a temporary magnet easily lose alignment, but the domains in a permanent magnet keep their alignment. there are domains in a permanent magnet, but not in a temporary magnet.

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)
