Changing states of matter

Matter is anything that has mass and takes up space.

The three states of matter are solid, liquid, and gas.

When a solid is heated, it can change into a liquid.

Melting is the process of changing from a solid to a liquid.

Freezing is the process of changing from a liquid to a solid.

When water freezes, it turns into ice, which is a solid.

Evaporation is the process of changing from a liquid to a gas.

Condensation is the process of changing from a gas to a liquid.

To dissolve means to mix a solid into a liquid so that it becomes part of the liquid.

Ice melts into water when placed in sunlight.
