If the co-efficient of performance of a refrigerator is 5 and operates at the room temperature `(27^(@)C)`, find the temperature inside the refrigerator.

Text Solution

Verified by Experts

`(Q_(2))/(W)=5, Q_(2)=5W`,
`Q_(1)-Q_(2)=W`
`:.Q_(1)=6W`
`(Q_(2))/(Q_(1))=(T_(2))/(T_(1))=(5)/(6)=(T)/(300)`,
`T_(2)=250K=-23^(@)C`
