Matter and Its States

In a cup of liquid water when would the water molecules stop moving?

• The molecules would stop moving if the liquid water in the cup became a solid.

• The molecules would stop moving if the liquid water in the cup became a gas.

• The molecules would stop moving if the liquid water in the cup became still.

• The molecules would not stop moving in the cup of liquid water.

Which state of matter will take both the volume and shape of the container that holds it?

• gas

• ice

• liquid

• solid

Why does water that is frozen in an ice cube tray stay in the shape of a cube when it is take out of the tray?

• The particles become locked in place

• The water particles stop moving completely

• The water particles grow bigger to fill the space

• The water particles can only slip past one another.

What is the role of heat when a gas changes state to become a liquid?

• the gas creates the heat

• The gas destroys the heat

• Heat transfers to the gas particles allowing them to gain energy

• Heat transfers away from the gas particles causing them to lose energy
