Phase Changes

When you heat a solid, what happens the the attraction between the particles within the solid?

• The particles become more attracted to each other

• The particle attraction doesn't change

• The particles become less attracted to each other

Critical Thinking! If gas particles in a tire are moving slowly, your tire pressure will drop because the gas particles are not pressing against the walls of the tire. What temperature change do you think would cause this pressure drop?

• The temperature will have become colder

• The temperature will have become hotter

• Temperature and pressure have no relation

Phase change between liquid and gas that takes place below boiling point without the addition of heat. This takes place at the surface of a liquid.

• evaporation

• boiling

• vaporization

• condensation

Phase change from a liquid to a gas that occurs when the liquid reaches its boiling point. This will occur throughout the liquid not just at the surface.

• vaporization

• evaporation

• melting

• condensation
