Question

A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced by 62°C the efficiency of the engine is doubled. The temperatures of the source and sink are

Answer 1

Answer:

source temp is 372k and sink temp is 310k

Explanation:

I explain in photo posted below

I want explain you that you may confused in units of k or 0c in this problem

remember change in temperature is denoted by any unit,but we have find the final answer in SI units therefore,final source and sink temperatures are in Kelvin units

hope you understand this.
