200 cal of heat is given to a heat engine so that it rejects 150 cal of heat, if source temperature is 400 K, then the sink temperature is

A

300 K

B

200 K

C

100 K

D

50K

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `(Q_2)/(Q_1)=(T_2)/(T_1)`
`implies T_2=(Q_2)/(Q_1) T_1=(150)/(200)xx 400` = 300 K.
