No. (Squeeze a balloon.)
An example of a physical change and a chemical change?
Melting of a solid to a liquid, or evaporation of a liquid to a gas. The physical state is changed but it is the same substance (though some substances do breakdown under heating, then it becomes chemical)
Is cutting your hair a physcial change?
Yes it is... The hair will grow back,but you're changing the physical appearance by cutting it. Chemically - it's still hair.
When you hit a piece of graphite and break it into small pieces you have broken chemical bonds?
This is FALSE ! Because you only broke it in pieces and tearing or breaking into pieces is a PHYSICAL CHANGE not a chemical change. ---------------------------- I also consider that breaking graphite is only a physical change. - - - - --------------------- It's true, you break chemical bonds when you break pieces of graphite. Graphite is a macromolecule: it is found in sheets, and within the sheets each carbon atom is bonded to four other carbon atoms. The only way you could possibly get it apart is to break the bonds between atoms.

Breaking glass is a physical change, as it does not change the chemical composition of the material.
Is bursting a balloon a physical or a chemical change?
When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.
