What else can I help you with?
Is hot soup cooling down a physical or chemical change?
Physical, largely by the evaporation of liquid water in the soup carrying of the heat as water vapor into the air.
Is cooling water vapour a chemical change?
yes it is
Is boiling water a reversible change?
Yes, the boiling of water can be easily reversed by simply cooling the water vapor.
Is the condensation of water vapor a chemical rection?
It is physical, change of state, just cooling down
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.
Is water changing from liquid to gas a chemical reaction?
No, water undergoing a phase change is a physical change, not a chemical change.
Is the condensation of water vapor a chemical change?
A phase change is not a chemical change since the chemical remains the same; water is still water, whether it is in the solid, liquid, or gas phase.
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.
Can heating water to change it to water vapor be a chemical change?
No, this is definitely a physical change, absolutely not a chemical.
Is water condensing a physical or chemical change?
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.
Is a chemical change when ice becomes liquid water?
No, it is a physical change
Is heat changing H2o to steam a physical or chemical change?
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply gaining enough energy to break free from their liquid state and form a gas. No new substances are formed in this process.
