A toucan is perched on a branch of a tree 18 meters above ground. If the mass of the toucan is 0.68 kg, calculate the energy of the toucan

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.
