Water in solid form, as ice, is chemically H2O
In liquid form it is also only H2O
In gas form, as water vapour, it is still only H2O, albeit that the molecules/atoms have greater activity and that the volume is much greater than that of water in the liquid state.
Physical
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Evaporation is a physical change.
The evaporation of salt water is a physical change because it does not alter the chemical composition of the water or salt. The water is simply changing from a liquid to a gas, leaving the salt behind.
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.
Evaporation is a physical change.
It is a physical change because the change is reversible.
This is a physical change.

No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
it is a physical change because it is not making a new substance. It is just changing the size/shape
Physical Change
Evaporation is a physical change.
No, evaporation of water from a lake is a physical process, not a chemical reaction. It involves the transformation of water from a liquid to a gas without any change in the chemical composition of water molecules.
