Heat transferred to a closed stationary system at constant volume is equal to
Detailed Solution for Mock Test: SSC JE (ME)- 6 - Question 4

The first law of thermodynamics is dQ= du+dw. (Where symbols have usual meaning) For a chemical system dw= pdv, but when the volume is constant, dv=0 and, dQ=du. So, under the condition of constant volume heat transferred is equal to the change in the internal Energy of the system.

Superheating in refrigeration cycle
Detailed Solution for Mock Test: SSC JE (ME)- 6 - Question 15

The refrigerators are the heat pumps which are used to lower the temperature of a given volume by doing work on fluid. The refrigerators work on a reverse Carnot cycle. The cool liquid passing through a chamber which is warmer does work on this fluid to convert it into the gaseous form thus lowering the temperature in the chamber. This process continues so as to bring the temperature of the chamber to a required temperature.

The quality or efficiency of performance of a refrigerator is determined by the coefficient of performance (COP) which is the ratio of the heat supplied or the work done by the air in the chamber to the work required by the system.

COP=Q/W

The work done W is the external work provided to the system for this non-spontaneous process to happen, in our case the electrical energy.
The superheating is the process in which the excess amount of heat is provided to the coolant. This increases the rate of cooling, which is a good indicator for COP.
But also, we should understand that if superheating occurs in a refrigerator, the external energy should be greater to keep the cycle moving.
From the above observations, the coolant evaporates faster adding efficiency of the system, on the other hand, the W required by the system increases, which clearly denotes a decline in the efficiency or the coefficient of performance of the refrigerator.
We get to know that the COP either increases or decreases when superheating takes place in a refrigerator, it is not consistent and therefore unpredictable.
