Answer:
Explanation:
Coefficient of performance (COP) of refrigeration cycle is given by:

We are given:


COP= 5
We can also write Coefficient of performance (COP) of refrigeration cycle as:

Amount of heat absorbed by low temperature reservoir can be found as:



According to first law of thermodynamics amount of heat rejected by hot reservoir is given by:



We are given the mass of 0.96 kg. So,



Since it is a saturated liquid-vapour mixture
.

From Refrigerant 134-a tables
at
is 61.3 C. (We calculated this by interpolation)
Converting
from Celsius to Kelvin:


We are given:
