Is steam condenses on a cold window chemical change?
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.
ice crystals forming on a window a chemical change?
No, ice crystals forming on a window is a physical change. A physical change involves a change in the form of a substance without changing its chemical composition. The water molecules in the air condense and freeze on the window, but they are still water molecules.
Are the salt crystals produced when a glass of saltwater is left on a window sill for several days a chemical or physical change?
The formation of salt crystals from saltwater on a window sill is a physical change. In this process, the water evaporates, leaving behind the salt crystals. The composition of the salt remains the same, so it is considered a physical change.

To condense is a physical or chemical change?
Condensation can be a physical process whereby a vapour becomes a liquid e.g. the 'steam' (water vapour) from your shower condenses on the bathroom window and runs down as water to form a puddle on the windowsill. Warm air can hold more water than cold air - the warm, vapour-laden air is cooled as it comes in contact with the colder glass and can hold less vapour so the surplus appears as water on the glass. In chemistry there are 'condensation reactions'
Is dew forming on a window considered a chemical change?
No, it is considered a physical change because chemically, water is still H2O, it has simply changed state by condensing.
If you break a window is it a physical change or chemical change?
physical.
Is steam condensing on a window chemical or physical change?
The condensation of steam on a window is a physical change. This process involves the transition of water vapor (steam) into liquid water as it cools upon contact with the cold surface of the window. No new substances are formed; instead, the water simply changes its state from gas to liquid.

Is breaking a window physical change or chemical change?
Physical Change, the window is still a window and you can get it back to its original state by re-melting it (although i dont see why you would want to do this). No new substace was formed, nor anything given off. :)

If frost forms on a window is it a physical chang or a chemical?
Physical- that is water vapor freezing into ice. It can be reversed (warm up the window) Chemical changes don't reverse.
Why is frost on a car window a physical change?
Frost forming on a car window is a physical change because it is a reversible process where water vapor in the air solidifies into ice crystals when it comes into contact with the cold surface of the window. The chemical composition of the water molecules remains the same before and after the frost forms.

Is thrown rocks physical change or a chemical change?
Throwing rocks is a physical change because it does not alter the chemical composition of the rocks. The act of throwing simply changes the position and motion of the rocks, but the rocks themselves remain unchanged chemically.
