heat
You must understand that matter 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>Liquid: Melting usually
Liquid>Solid: freezing, or hardening(like cement or clay)
Liquid>Gas: evaporating usually
Gas>Liquid: condensing(like the condensation of water on glass)
Solid>Gas: sublimation(dry ice does this)
there are 6 states of matter ,solid,liquid,gas,plasma, Bose-Einstein condensate,fermionic condensate.
heating up and cooling down will effect the state of matter. for an atom to turn into a fermionic condensate or Bose-Einstein condensate it must be cooled to temperatures of less than 3 kelvin (around -270'c)
Chemical change
Any type of reaction, really. You could add heat or remove heat (thermal energy) to cause the matter to change phase. Also pressure can compress the matter into a new form.
There are 2 kinds of changes,they are physical and chemical changes.Physical Change-is a change in the form of matter but in it's identity.Chemical Change-is a change in which one kind of matter is changed in to a different type of matter.
this model of the rock cycle shows how rocks change from 1 form to another
it is a physical change since it can be reversed to its original form.
You think probable to chemical reactivity.
A change of matter from one form to another without a change in chemical properties is a physical change.
A change of matter from one form to another without a change in chemical properties is a physical change.
it puts force on an object to make it move and makes matter change
A physical change occurs.
By adding heat and removing heat.

A change in the physical state of matter is a physical change.
Any type of reaction, really. You could add heat or remove heat (thermal energy) to cause the matter to change phase. Also pressure can compress the matter into a new form.
Liquid. And gas, and solid. Plasma is another form of matter, but it is not common.
A physical change is a change in the form of matter but not the chemical composition of it.
Yes. I pick up my pencil and put it in my pocket. It has not changed form and has been moved.
Yes - its another word for vapor - which is another word for gas, which is a form of matter.
