Water evaporating is probably one the most critical things that occurs in nature in order for us and other life form to exist. It is of course a physical change, because the water molecule that has evaporated still has the potential to turn back into water and keep it's previous qualities of a water drop. A chemical change is where water is mixed with another liquid and it's molecular structure changes, even in liquid form. Water becomes a gas because the water drop has billions of molecules in it's chain, that are held together by electrical forces. These molecules are constantly vibrating at terrific speeds, the hotter the temperature, the faster the molecules vibrate. So when the water becomes too hot, the molecules vibrate so extensively that they overcome their bonds and fly apart. This is why when water boils, the oxygen and HO molecules that have overcome their bonds rapidly rise to the surface and make the water uneven when it boils.

No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
It is a physical change.
Yes, gas bubbles forming in boiling water is a physical change because it does not alter the chemical composition of the water. The bubbles are simply the result of water vaporizing into steam due to the increase in temperature.

Condensation of water is a physical change.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
No, this is definitely a physical change, absolutely not a chemical.
