An ideal refrigerator keeps its content at `0^(@)C` while the room temperature is `27^(@)C` .Calculate its coefficient of performance.

Text Solution

Verified by Experts

Content placed at temperature `T_(L)=0^(@)C+273=273K`
Room temperature `T_(H)=27^(@)C+273=300K`
Coefficient of performance `beta=`?
`beta=(T_(L))/(T_(H)-T_(L))=(273)/(300-273)-(273)/(27)`
`beta=10.11`
