Carnot Refrigerator

If the work done by a Carnot engine working between two temperatures 600K & 300K is used as the work input in Carnot refrigerator, working between 200K & 400K, find the heat (in J) removed from the lower temperature by refrigerator? The heat supplied to engine in 500J

A Carnot refrigerator extracts heat from water at 0^@C and rejects it to room at 24.4^@C . The work required by the refrigerator for every 1 kg of water converted into ice is (Latent heat of ice= 336 kJ kg^(-1) )

Carnot Engine and Refrigerator

A refrigerator is

Carnot Cycle Efficiency || Refrigerator || Effect OF Performance

Cyclic Process | Efficiency of a cyclic process | Heat engine and refrigerator | Carnot cycle | Mean free path

The temperature of food material in refrigerator is 4^(@)C and temperature of environment is 15^(@)C . If carnot cycle is used in its working gas, then find its carnot efficiency.
