What changes a liquid or a solid to a gas?
usually a change in temperature.... OR PRESSURE Which all mean a change in entropy of the system
What is true about entropy?
Entropy is not change. Entropy is disorder.
Function of entropy in climate change?
The climate is not affected by entropy.
What is randomness or chaos in chemistry?
The amount of disorder/randomness of a system is called the entropy of the system.
What does the second law of thermodynamic say about entropy?
The entropy of the universe is increasing
What does negative change in entropy indicate?
The system has become more ordered.
What does a negative change in entropy indicate?
The system has become more ordered.
How does the entropy of a system change for condensation of water?
The entropy is lower.
According to the second law of thermodynamics does entropy increase in a cold system?
That depends on what you mean by "cold" system. Entropy in any system can do one of three things: increase, decrease, or remain constant. If the system is closed, then entropy will only ever increase. If the system is open, entropy within it can do any of the three, provided there is a corresponding change in entropy outside the system (energy must come from or go to somewhere to effect an entropy change). The absolute amount of energy in the system makes no difference to the entropy of it. It is whether you have an open or closed system that counts.
What is S in the equation G = H - TS?
The change in entropy between products and reactants in a reaction ap3x answer
Is it possible for entropy to be negative and For entropy change to be negative and For entropy production to be negative?
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
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.
Is Delta S is the change in enthalpy a measure of randomness?
No, delta s is the change in entropy. Delta H is the change in enthalpy, the amount of heat used in a system. Entropy and enthalpy are different, but closely related.
Are all reversible processes is entropic?
Yes. Isentropic means "constant entropy." For all reversible processes, the change in entropy for the system and its environment is zero.

What is the measure of disorder and randomness?
Entropy is the measure of system randomness.
What is true about entropy?
Entropy is not change. Entropy is disorder.
