Question

A piston-cylinder device contains helium gas. During a reversible, isothermal process, the entropy of the helium will _________ increase. During a reversible, adiabatic process, the entropy of the helium will ____________ increase. During an actual adiabatic process, the entropy of the helium will ________ increase.

Answer 1

Answer:

During a reversible, adiabatic process, the entropy of the helium will NEVER increase.

During a reversible, isothermal process, the entropy of the helium will SOMETIMES increase

During an actual adiabatic process, the entropy of the helium will DEFINITELY increase

Answer 2

A piston-cylinder is a moving device that is made tight by the piston rings. It moves inside in a cylinder in the form of liquid and later expands and then contracts.

• A piston-cylinder consists of helium gas and during the reverse process of the isothermal activity, the entropy of the helium gets sometimes increased.

Hence the helium gas sometimes will increase
