It is a physical change because it hasn't changed materials it just changed they way it look without adding or taking away substances. It will always be a window.
A physical change.
Yes!
physical.
The window cracked for no reason due to a sudden change in temperature or stress on the glass, causing it to break spontaneously.
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.
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.
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. :)
True.
Water vapor condensing on a cold window is a physical change. It is simply a change in state from a gas (water vapor) to a liquid (water) due to the temperature difference. No new substances are formed during this process.
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 fix a cracked window, you can use a glass repair kit or call a professional glass repair service to replace the glass pane.
