The change in state from liquid to gas is known as

• Melting

• Freezing

• Evaporation

• Sublimation

A substance that takes the shape of and always fills it's container could be:

• Oxygen

• Wood

• Cordial

• String

Diffusion occurs when

• A candle is blown out

• A bomb is deactivated

• A gas is compressed

• A solid or liquid turns into a gas

Which list below gives the states of matter in order, from ‘the closest packed particles’ to ‘the most spread out particles’?

• gas, liquid, solid

• liquid, solid, gas

• solid, gas, liquid

• solid, liquid, gas

Which diagram best represents a substance that is frozen?

• 1

• 2

• 3

• 4

Which of the following is true about particles?

• They never move in solids

• They only move in gases

• They never move

• They move most in liquid and gas form

As the temperature of a substance increases, it's particles:

• Move faster

• Move slower

• Move at the same speed, but further apart

• Stick together more

Which of the following are best at diffusing?

• Solids

• Liquids

• Gases

• Clouds

The picture shows the arrangement of particles of a substance in three different states. Which of the following must be true?

• Particles on the left move faster than the particles on the right

• Particles on the right will spread out to fit whatever container they are in

• Particles on the left and in the middle are locked in place

• Particles in the middle are affected by electric and magnetic fields

A metal ball just fits through a metal ring at room temperature. If you heat the ball only:

• The ball will easily fit through the ring

• The ball will not fit through the ring

• The ball will continue to just fit through the ring

• The ball will compress to fit through the ring
