.85-120 Thermodynamics Tutorial 3 Problem 1. An inventor claims to have invented 4 engines, each of which operates between constant-temperature reservoirs of 400 and 300 K. Consider the 1st and 2nd laws of thermodynamics to evaluate the engines. For each engine, state and explain why it does or doesn't violate the 1st and 2nd Laws of Thermo. 1st law hint: Think quantity of work. 2nd Law hint: Think process efficiency.
