Astraightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. what is the density (in g/cm3) of a 300 g rock that displaces 89.0 cm3 of water? (note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on archimedes' principle.)

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.
