Changing state is a physical change. The chemical composition of the substance doesn't change, only the form the substance takes. Liquid water changing to ice is still water-- the chemical composition hasn't changed.
An example of chemical change would be methane (CH3) burning in oxygen (O2) to form carbon dioxide (CO2) and water vapor (H2O). The methane and oxygen no longer exist as themselves but have become carbon dioxide and water vapor-- their chemical compositions have changed.

The explanation is that this change of state doesn't change the chemical composition.

Is condesing a chemical change?
No, condensing is a physical change, not a chemical change. It is the process of changing a substance from a gas state to a liquid state by removing heat energy.
Is sublimation of mothballs physical or chemical change?
Physical, since it's just changing the state of matter
Is concrete setting a physical or chemical change?
It would be both. It's a physical change because it is changing state and a chemical change because water is being evaporated.
Is changing from a gas to a liquid a chemical change?
No, changes of state such as this are physical changes.

Is liquid becoming a gas a chemical change?
No, a liquid changing to a gas is a change of state or a physical change.
Is the change of state a physical?
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.
Is a physical change a change of state?
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.
