The total entropy of steam at critical pressure and temperature is equal to 1.0785 btu/lb.
(as liquid water does not exist at critical pressure and temperature the entropy of liquid is 0)

What the example of the statement the entropy of the universe can never decrease?
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
When will be entropy negative?
It won't. Entropy always increases.
Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
What happens to entropy when energy is transformed?
There is always an increase in the entropy of the universe.
Which thermodynamic law has to do with entropy?
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
What is the point on a phase diagram at which all phases occur simultaneously is called the end point critical point boiling point melting point?
This is the critical point.
What is the scientific measure of disorder is called?
This is called entropy.

What is difference between critical temperature and boiling point?
difference between critical temp and boiling point
What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
What is true about entropy?
Entropy is not change. Entropy is disorder.
What is critical heat flux and what is its physical significance?
critical heat flux is the heat flux at critical point
What is the critical temperature and pressure of CCl4?
For example from hydrogen critical point (-239,85 0C) to lithium critical point (2 950 0C).
What does the critical point represent?
Critical point is also known as a critical state, occurs under conditions at which no phase boundaries exist. There are multiple types of critical points, including vapor-liquid critical points and liqui-liquid critical points.
What happens when to the entropy when a solution is made?
The entropy increases.
What is the measure of disorder and randomness?
Entropy is the measure of system randomness.
How does density vary for a component at its critical point?
For a pure component the density difference between a liquid and gas approaches zero as the critical point is approached. By definition liquid and gaseous phases are indistinguishable (meaning no difference) at the critical point.
