Is it a physical change chemical change when salt dissolves in water?
Physical
What is physically happening when water is dissolving a substance?
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?
Dissolving in water is a physical change.
What property chemical or physical would best describe the process of water evaporating from the oceans to begin the water cycle?
evaporation is a physical change
Is it a physical change chemical change when salt dissolves in water?
Physical
Why is water evaporation a physical change and not a chemical change?
Nothing is chemically changed when water goes from liquid-->gas. All that's happening is the molecules moving faster. H20(l)-->H20(g)
Describe what is happening to water molecules as ice melts?
they move faster

When water is boiled is it a chemical or physical change?
Boiling is a physical phenomenon, a change of phase.
Is water absorbed by a paper towel a physical or chemical change?
It is a physical change.
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.
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 condesning water a chemical or physical change?
Condensation of water is a physical change.
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.
Is mixing oil and water a chemical change?
Oil floating on water is not a "change", so asking whether it's a physical change or a chemical one is nonsense. To the extent there's any meaning at all to the question, it's a phenomenon caused by the physical properties of the two materials.
