Crystalline Solid. Amorphous Solid. Graph showing change in temperature vs time. When the particles have gained enough energy they will break free of some of the attractions between them and the other particles allowing them to move more freely through out the substance.

When the particles have gained enough energy they will break free of some of the attractions between them and the other particles allowing them to move more freely through out the substance.
During the change in state the temperature remains constant. This is because the energy is being used to break particle attractions.
The process by which a liquid becomes a gas is called vaporization.
The process by which a gas becomes a liquid is called condensation.
While vaporization and condensation are taking place there is no change in temperature because the energy changes are associated with changes to particle attractions.
Evaporation occurs because some of the particles in a sample have enough energy to escape.
Some materials can undergo a change in state between the solid state and gaseous state without becoming a liquid.
