Entropy is a measure of the amount of disorder a system has. More accurately the amount of work that can be extracted from a system. The more entropy a system has the less work that can be done. 1kg of steam at 500 degrees can do lots more work than a kilo of warm water. Entropy always increases in a closed system. Entropy is why everything eventually breaks down.
This is called entropy.
Entropy is not change. Entropy is disorder.
The entropy increases.
Entropy is the measure of system randomness.

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.
Of, relating to, or being a reversible thermodynamic process that occurs without gain or loss of heat and without a change in entropy. Source: Anwers.com

No, entropy is a state function.
It won't. Entropy always increases.

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.
