Solid, liquid, and gas

Matter is defined as…

Anything that has mass and takes up

space

The particles of matter are called…

Molecules

The molecules of this type of matter are attracted to each other, but able to move past each other.

Liquids

When the particles of a liquid are heated, what happens to the speed and space between the particles?

The particles increase in speed and increase in space

Cooling a liquid _______ the speed of the molecules and _______ the space between them.

decreases and

decreases

This is diagram of room-temperature water.

Draw the particles of cold water and hot water.

Gas is matter

because it…

What happens to a solid that is cooled?

The molecules vibrate slower and pull closer together.

Draw a diagram of each type of matter at room temperature.
