Idon't really understand. worth 12 points!
heat = mass(m) * specific heat capacity(c) * temp. change(delta t)
itembank:
a.) 1.04kj
b.) 10.4 kj
c.) 14.5 kj
d.) 44.8 kj
match each item from the item bank to its corresponding match:
1.)heat = mass * c * temp change
175g 0.79j/gc 75 c
2.)heat = mass * c * temp change
352g 1.65j/gc 25 c
3.)heat = mass * c * temp change
268g 4.18j/gc 40 c
4.)heat = mass * c * temp change
74g 0.21j/gc 67 c
i don't have to have the answer to all of them; i just need understanding what to do.

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.
