Engineering Thermodynamics MCQ with Answers

101) Carnot cycle has maximum efficiency for

Answer is:

reversible engine

102) Measurement of temperature is based on

Answer is:

zeroth law of thermodynamics

Explanation:

Zeroth law of thermodynamics : Zeroth law of thermodynamics states that, when two bodies are in thermal equilibrium with a third body. They are also in thermal equilibrium with each other. Measurement of temperature is based on zeroth law of thermodynamics.

103) Carnot cycle efficiency depends upon

Answer is:

temperature range of operation

104) Carnot cycle efficiency is maximum when

Answer is:

final temperature is 0°K

105) An engine operates between temperatures of 900°Kandr2 and another engine between T2 and 400°K For both to do equal work, value of T2 will be
