If the entropy decreases through a turbine with no changes in height or kinetic energy then which statement must be true about the system?

Question 6 options:

	Enthalpy increased through the turbine.
	The working fluid is an ideal gas.
	The process is not adiabatic.
	Irreversibilities exist within the process.

Steam (water vapor) is an example of a substance which may always be considered to be an ideal gas

Question 7 options:

	True
	False

Entropy is generated within a system by reversible processes at the boundary of the system.

Question 5 options:

	True
	False

Entropy is transferred into or out of a system through heat transfer.

Question 4 options:

	True
	False
