Although you may not be able to observe the particles in matter moving, how can you detect the motion?

• by the material’s weight

• by how warm or cool a material is

• by the way the material moves up and down slightly

• by the material’s vibration as it goes through your hands

Why do air particles move slower on a chilly morning than they do on a warm afternoon?

• The air’s particles get blown around by the wind in the afternoon.

• The air’s particles are trapped close to the ground on a chilly morning.

• The air's particles move slower when cool and move faster when warm.

• The air’s particles die off in the night and there are fewer of them left in the morning.
