5. in a lab experiment, 45 grams of a metal are heated from 22⁰c to 78⁰c by the addition of 450 j of heat. what is the specific heat of the metal? show all calculations leading to an answer.

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.
