No, they are completely different things.
The entropy increases. The runny water is more disordered than the rigid ice-cube and entropy is like disorder so there is more entropy too. Another way of looking at it is this. The ice melts because it is in a warmer room. It is natural for all things in a room to get to the same temperature. Things which happen to get back to the natural state are usually things where entropy increases.
Entropy is not change. Entropy is disorder.
Actually its a bit Controversial, when we say Entropy, alot of things come into picture. So U just can't say Entropy is increasing. But in accordance with 2nd law of thermodynamics, it is true. U have to consider a particular system and its surroundings, then study its stability and 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.
No - to straighten a messy room requires work, and in the process energy is released as heat into the environment. The room may become more orderly, but the net effect on the universe is an increase in entropy because of the heat released.

This is called entropy.

In simple terms, the entropy, or disorder, in the universe is always increasing. As for how, well it's one of those things you get or don't get. There can be times when the system is decreasing entropy but the surroundings are increasing entropy and things like that, but no matter what the entropy of the system (universe) as a whole is always increasing. The easiest way to understand would be to look at some common chemical equations. The most obvious is a solid or liquid going to a gas because gas molecules are more random/disorderly and they tend to be smaller and in their "pure" forms so more molecules are made which also leads to increased entropy. Basically there's no one answer, you'll just have to study all the different possible cases. There are less obvious entropy equations as well. Other things like temperature and pressure can affect entropy too.
you should not leave your things messy .
They HATE messy diapers.
Entropy is not change. Entropy is disorder.
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.
Things will likely get very messy and unpredictable.

The entropy increases.
