when we dissolve a substance then first of all there may occur physical change like shape,colour,temperature etc. these changes are called physical changes.
Is separation of water and gasoline a physical change?
No, it is a physical change. The water and gasoline retain their chemical and physical properties.
Is evaporating water a physical change or 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.
Solid forms into dissolved water is a chemical or physical change?

What property chemical or physical would best describe the process of water evaporating from the oceans to begin the water cycle?

How are the terms physical property and change related?
Physical change rearranges the molecules. The internal structures are not affected. eg. water when frozen, changes into ice. The water molecules are just stuck together and it is still water. The physical property of any matter can exist in any three physical states and are only used to describe and observe the matter.
Is boliling water a chemical or physical change?
Boiling water is a physical change because it does not change the chemical composition of the water.
What is a result of a physical change of water?
