It is a physical change : P Physical changes are mainly when: -Something
No. It is a physical change as the actual compound does not change, only its state does.
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.
No, the evaporation of sweat is a physical change, not a chemical change. Evaporation simply involves a change in state from liquid to gas, without any change in the chemical composition of the substance.
It's a physical change because no new substances are formed, the molecules simply get further apart.
Sweating and evaporating are similar because evaporating is the change of liquid water to water vapour, which requires heat, and sweating is where the skin produces liquid sweat, which is a mixture of water and other substances, which absorbs heat from your skin as it is transformed into a vapour. As you see, when you sweat your sweat is actually evaporated into the air, while absorbing your body and cooling you off!!
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.
Yes, it is.

Yes, evaporation is a physical change of phase.
Evaporation is a physical change.

Evaporation is a physical process.
Physical Change
it is a physical change. It's obvious becuase it is just a change of state
physical change, its molecules are gaining energy and evaporating
Yes, this is a physical change.
