A refrigerator works between 4^(@)C and ...

A refrigerator works between `4^(@)C` and `30^(@)C`. It is required to remove `600 calories` of heat every second in order to keep the temperature of the refrigerator space constant.The power required is (Take `1calorie= 4.2 J`)

A

`2.365W`

B

`23.65W`

C

`236.5W`

D

`2365W`

Text Solution

Verified by Experts

The correct Answer is:
C

`beta=(Q_(2))/(W) = (T_2)/(T_(1)-T_(2))`
Where `Q_(2)` is heat removed)
`implies (600xx4.2)/(W) = (277)/(303-277)`
`implies W = 236.5joule`
