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)`
`(2520)/(W)=(277)/(303-277) rArr W="236.5 joule"`
Power `=W/t=(236.5)/(1 sec) " joule=236.5 watt"`
