When water changes from a gas to a liquid it is still called water, but I don't think that was your question. The process of changing water, or any substance for that matter, from it gaseous state to it liquid state is called condensation,
Clouds! The fact that a cloud "looks like" something is a property of where the viewer is in relation to it. A. To you it looks like something, to someone looking at it from even a mile away it looks completely different. B. To you - now - it looks like something, to you in ten minutes time, still in the same place, it looks completely different. There is no name for this phenomenon..... mainly because the "looks like" is only in our mind. C. To you it looks like something, you tell the person beside you and they can't see the resemblance at all.
Yes, evaporation, melting, and freezing are all physical changes. For it to be a chemical change, the substance would have to become a different substance. Evaporated ethanol is still ethanol, it is just in gas form.
no, then it is gasEDIT: The chemical formula for pure water is always H2O - regardless of whether it's in the form of ice, water or steam ! Snakester1962 (Supervisor)

When the state changes, it won't be the same shape because there are different properties for each of the states, e.g. liqiud can fill any shape but moves to the bottom, solid can't move and gas fills any shape. It will have the same amount of substance because it is still the same thing, just in a different state.
it can be easily reversed because nothing new is produced. it is the same particles but just rearranged. it is just a change in size, shape or state ***IT IS REVERSIBLE*** but what physical change is not easy to reverse?
A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
Well... I have a son, even though I am 14, but still he looks, NOTHING like me, but I still know he is, but if he is Zeke, then he is NOT your own child, he is from a different planet
The identity of the property does not change so the physical properties change but not the chemical
pig on these are both words that look different but are still a word upside down.
Because it is still paper but it looks different than before. That help?
No. It is still the same matter, just in a different state.
If you win the lottery in a different state, you can still claim your prize, but you may have to pay taxes in both the state where you bought the ticket and the state where you live.
No, liquid water changing to a gas (water vapor) does not involve a change in chemical composition, so it does not become a new compound. It is still composed of H2O molecules, just in a different state of matter.
