Is evaporation a chemical or physical change?

Answer 1

While boiling isn't the same as evaporation in that the entire liquid is heated to the point of steam and not just the surface molecules, the same physical change that causes evaporation can be seen in boiling. When boiled, a liquid becomes hot enough that it converts from that form into a gas, and if gathered and cooled, that gas reverts to its liquid form. For example, if a pot of boiling water is covered to trap the steam, that steam gathers on the inside of the cover where it again becomes water. This not the result of any chemical change in the water, just a change in its physical form.

SO, EVAPORATION IS A PHYSICAL CHANGE.

Answer 2

A liquid evaporating is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).

Answer 3

Evaporating is a physical change. When water evaporates, it is still water, just in a different form. Since it is the same substance, it is a physical change.

Answer 4

Evaporation is a physical change. The chemical makeup of the gas is still the same as the liquid. Only the physical state has been altered.
