Question

Compare and contrast the physical properties of solids liquid and gases?

Answer 1

Physical properties of phases, at standard temperature and pressure:

Solids - Keep their shape

              Definite mass ( will not change in size )

              Definite volume ( will not change shape )

              High melting point

              Molecules vibrate slowly in place

              Are.. well... solid.

Liquids - Take shape of container

                Definite mass

                Indefinite volume ( will change in shape under certain               conditions )

                Molecules vibrate rapidly and freely

Gases - Take shape of container and fill completely

                Indefinite mass and volume

               Expand rapidly and evenly to fill container

               When released in large area ( class room, outside, outer space, ) will fill entire area and become extremely scarce.

Hope that helps :D
