An inventor claims a new cyclic engine that uses organic grape juice as its working material. According to the claims, the engine absorbs 1220 J of heat from a 1020 K reservoir and performs 1110 J of work each cycle. The waste heat is exhausted to the atmosphere at a temperature of 352 K . Part A What is the efficiency that is implied by these claims? e e = nothing

.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. Engine 1 2 3 4 QH (J) 200 500 600...
