Physical change- it is still H2O, and can be changed back to water by cooling it.
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.
No, condensation of steam on a cold window is a physical change, not a chemical change. The water vapor in the steam undergoes a change in state from gas to liquid as it loses heat energy to the cold window, but the water molecules themselves remain unchanged.
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
It's a physical change because no new substances are formed, the molecules simply get further apart.
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
physical only, you are only changing its state, not its composition.
It is a physical change because it's still a form of water just a different state.

No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
It is a physical change because the change is reversible.
