E-Lecture - Expansion of liquids

The force between particles in liquids is not as strong as that between particles in solids. As a result, for a given change in temperature liquids expand or contract faster than solids.
The formula used to calculate change in volume for a change in temperature of a solid can be applied for liquids. However, why we want to discuss volume expansion for liquids is that liquids are treated with their containers and consequently the expansion of the container affects the result for liquids.
