Solution:
The efficiency of a carnot engine is:
1- T2/T1 = 1-150/200 = 1/4.
Efficiency is also given by: 1 – Q2/Q1 = 1 – Q2/1200 = 1/4.
Q2 = (3/4 )1200 = 900J.
A carnot engine extracts 1200J of energy from a hot reservoir. What is the amount of work done by it? Temperatures of hot and cold reservoirs are 200K and 150K respectively.
