A physical quantity that is the measurement of the amount of disorder in a system.
This is called entropy.
Entropy is not change. Entropy is disorder.
The entropy increases.
Entropy is the measure of system randomness.
entropy
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
The entropy of the universe is increasing
No, entropy is a state function.
It won't. Entropy always increases.
positive
Entropy is a measure of the disorder or randomness in a system. The phase of matter with the highest entropy is generally considered to be the gas phase, as the particles in a gas have the highest degree of freedom and randomness compared to liquids and solids.
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.
