i need correct solution

A Carnot engine has an efficiency of 31.2%. It operates between constant-temperature reservoirs differing in temperature by 1

Answer 1

Answer #1

T1 - T2 = 140

T2 = T1 - 140.. (i)

Now as we know

n = 1 - T2 / T1

0.312 = 1 + 140 / T1 - 1

T1 = 448.72 K ==>> ( hot reservoir)

putting in (i)

T2 = 308.72 K ===>> (cold reservoir)

=========

Comment before rate in case any doubt, will reply for sure.. Goodluck
