Why is condensation of water vapor is a chemical change?
Condensation of water vapor is a physical change, not a chemical change. It involves the transition of water vapor into liquid water due to a decrease in temperature, without any change in the chemical composition of water molecules.
Is evaporation a chemical change?
No, evaporation is a change from liquid to gas (water vapour).
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
Is rain evaporation physical or chemical?
Physical change from liquid to vapour. The water remains chemically the same whether liquid or vapour.
What is evaporation condensation?
Evaporation is the process of water becoming a vapour. Condensation is the cooling of the water vapour back into a liquid.
Is cooling liquid water to form ice a chemical change?
No. Freezing is a physical change.
What is the chemical formula for water- water vapour?
h20
Is steam a chemical raection?
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
Is vapor a chemical change?
no as it can be turned back to water or be freeze to ice by over cooling.
What is the process of cooling down of water vapour called?
The process of cooling down water vapor to form liquid water is called condensation. This occurs when the temperature of the water vapor drops below its dew point, causing it to change phase from gas to liquid.
Is change in state a physical change?
Yes, because the chemical composition remains unchanged. Water is still H2O whether it is solid, liquid or a vapour.
Why is the boiling point of water a physical change?
It's not a chemical change because the only the temperature and phase changes. The properties may be altered somewhat, but it the same chemical compound. No atomic bonds are broken or formed, there are no new substances formed, and none of the signs that indicate a chemical change are present. Some of the water is changing from a liquid to a gaseous state, and can be returned to a liquid state, unchanged, by cooling it.
