Answer to Question #280714 in Molecular Physics | Thermodynamics for Teju

Question

An inventor claims to have developed an engine working between 600 K and 300 K capable of having an efficiency of 52%. Comment on his claim.

Answer 1

Solution:

 It is possible for the engine to have an efficiency of 52%. Dividing 300k by 660k and then subtracting the answer from one will lead to 0.54 which translates to an efficiency of 54%. Therefore, between 660k and 300k it is possible for the investors' engine to obtain an efficiency of 52%.
