I know that there is laws of physics. Such as, water boils when you reach x temperature and water freezes when you reach y temperature. BUT, do we know why water boils at a certain temperature and freezes at a certain temperature? Or not yet...??

There's this nifty little chart about states of matter, and it shows where what matter while be in what state given a certain pressure and temperature.
Think about atoms like popcorn. You heat em up, they start to bounce back and forth, and then they're out of the bucket, or making the bag expand. Water does the same, when you heat it so much, the molecules will bounce off each other but instead of falling out into a bucket, they turn to steam.
If you had a whole lot of bouncy dog toys, you wouldn't be able to stack them up nicely while they were all turned on. You'd have to turn them off so they fell into position and stayed there. That's what happens when water freezes, it loses energy (think of amount of energy relative to it's heat)
Why it happens at the degrees we have them at depends on the makeup of the molecule, because of it's shape, it's electron clouds, it's molecular weight...
hope that helps some

What you described was only a phenomenon (the points when water freezes and boils) that the laws of physics can explain. Laws of physics are fundamental rules that not only explain prevailing phenomena but are also consistent with each other (meaning one law should not be make another law invalid) and can predict the outcome of hypothetical situations.

Frozen water or ice as it is called is water in it's solid state. Water as you know it is the liquid state. Boiling water is the act of changing from a liquid state to a gas. Dry ice as it is called is carbon dioxide in it's solid state. Sublimation occurs when it warms up and changes directly to a gas. These things I am quite sure fall under the title of chemistry.not physics.

Yes, I think as the vibrations of the bonds increase or decrease with tempreture, and so, when heated the bonds vibrate so much that they break and turn to gas.
