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 temeprature `T_(L) = 0^(@)C + 273`
`= 273 K`
Room temperature `T_(H) = 27^(@)C + 273 = 300 K`
Coefficient of performance `beta = ?`
`beta = (T_(L))/(T_(H) - T_(L)) = (273)/(300- 273) = (273)/(27)`
`beta =10. 11`
