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.
Physical, a chemical change is when a substance's chemical configuration is altered, like an ozone molecule breaking into single oxygen molecules from CFC.

Is steam a chemical raection?
No, steam is not a chemical reaction. Steam is the gaseous form of water when it reaches a high enough temperature to evaporate. It is a physical change, not a chemical one.
When water changes to steam is it a chemical change?
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.
Is production of steam a chemical or physical change?
The production of steam is a physical change. It involves the phase transition of water from a liquid to a gas without any chemical change in the substance.
When water changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
Is steam condensing on a mirror a physical change?
Yes, steam condensing on a mirror is a physical change. It involves the change of state from gas (steam) to liquid (water) without any chemical reaction taking place.
If you have steam in a test tube which condenses to moisture-is this a physical or chemical property?
You have a phase change which would indicate a physical change since the substance remains the same in composition.
Is mixing popcorn steam a physical or chemical change?
it is a chemical change
Water is heated and changed to STEAM?
That is called boiling. And it is something you can see and observe, but it is something tht is chemically relted and so it is a chemical change.
Is water is heated and changed to steam a physical change or chemical change?
chemical
Is steam a chemical raection?
No, steam is not a chemical reaction. Steam is the gaseous form of water when it reaches a high enough temperature to evaporate. It is a physical change, not a chemical one.
What happens to the particles when steam condenses onto a cold mirror?
When steam condenses onto a cold mirror, the water vapor in the steam loses energy to the cold surface of the mirror. This causes the water vapor to change phase from gas to liquid, forming water droplets on the mirror's surface.
When water changes to steam is it a chemical change?
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.
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
What happens to energy when steam condenses to water?
When steam condenses to water, it releases the latent heat it absorbed during the phase change from water to steam. This heat energy is transferred to the surroundings, leading to a temperature decrease in the steam as it turns into water. This energy release helps to warm the environment around the condensed water.
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
Is steam from a kedal a physica l or chemical change?
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
Is boiling water into steam is chemical change?
yes
