Question

According to the statement of Clausius, Heat can be moved from TL to TH with W-0. True False QUESTION 3 10 points Save Answer A perpetual-motion machine of the second kind is the machine which makes an energy conversion that violates the second law of thermodynamics. True False QUESTION 4 10 points Save Answer In a reversible adiabatic process, the specific entropy is constant. True False QUESTIONS 10 points Saved An isentropic process is a polytropic process. True

Answer 1

Answer 1

False

As The Clausius statement is related to the everyday observation that heat never flows spontaneously from a cold object to a hot object.

Answer 2

True

Perptual motion machine is second kind of machine it violates the Second law of thermodynamics. Heat cannot be transferred from a colder to a hotter body.

Answer 3

True

In reversible adiabatic process change in entropy is zero.
