physical change, its molecules are gaining energy and evaporating
No, sweat evaporating from your forehead is a physical change, not a chemical change. The sweat is merely changing from a liquid state to a gas state without any change in its chemical composition.
it is a physical change since water and water vapor has the same chemical composition which is H2O. there is only a change in phase from liquid to gas. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
Water evaporating from a puddle is a physical change. During evaporation, water changes from a liquid to a gas, but its chemical composition (H₂O) remains the same. This process is reversible, as the water vapor can condense back into liquid water. Therefore, it exemplifies a change in state rather than a change in chemical identity.
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
When water evaporates, it is a physical change.You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.

No. It is a physical change as the actual compound does not change, only its state does.
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).-Alec Vasquez
The evaporation of water in a lake is a physical change. This is because the water is changing state from liquid to gas without any change in its chemical composition.

Evaporation of water from a lake is a physicalchange.They are still water molecules whether in the state of liquid, solid or gas. There has been no chemical change.

Yes. Evaporation is a physical change of state. In the case of evaporation enough heat, called the Latent Heat of Vaporization, is added to a liquid to change it from liquid to gas.
It's a physical change because no new substances are formed, the molecules simply get further apart.
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
Water evaporating from a puddle is an example of a physical change, specifically the transformation of liquid water into water vapor. This process involves a change in state from liquid to gas without altering the chemical composition of the water molecules.
