Condensing water vapor is a physical change. During condensation, water vapor transitions from a gas to a liquid without altering its chemical composition; it remains H₂O. This process involves changes in energy and state but not in the molecular structure of the substance.
No, this is definitely a physical change, absolutely not a chemical.
water forming water vapor is physical change
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
No, this is definitely a physical change, absolutely not a chemical.

Condensing water vapor into rainfall is a physical change. It involves a change in the state of water from gas (water vapor) to liquid (rainwater) without altering the chemical composition of water molecules.
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.
Sublimation of iodine to iodine vapor is a physical change. It is a phase transition in which a substance goes directly from a solid to a gas without changing its chemical composition.
Water vapor is in the gaseous state.
Yes, as the water does not undergo an inherent change in its chemical makeup.
No. It is a physical change.

Dew results from a physical change; water vapor condenses to become liquid water. Since it is still water, it has not experienced a chemical change.
A physical change is something that does not change the chemical makeup of a substance. For example, water turning into vapor is a physical change because the composition is not changed. Water vapor still has hydrogen and oxygen just like water.
The formation of fog is a physical change, not a chemical one.
