What is the name given to the change state from a gas to a solid?

• sublimation

• reverse sublimation

• evaporating

• condensing

Which statement best describes the fact that gases can be compressed?

• The particles in a gas do not have a fixed volume.

• The particles in a gas are very far apart.

• The particles in a gas have no force of attraction (bonds) between them.

• The particles in a gas are constantly moving very rapidly.

Which statement best describes the fact that a liquid cannot be compressed?

• The particles in a liquid are all close and touching.

• The particles in a liquid are constantly moving.

Which statement(s) best describes the fact that a liquid flows?

• The particles in a liquid have weak bonds between them.

• The particles in a liquid have no fixed position.

• The particles in a liquid are close and touching.

• The particles in a liquid are moving slowly over each other.

Diffusion occurs in which states of matter?

• Solids

• Liquids

• Gases

When a liquid evaporates the temperature of the liquid decreases. Which statement(s) best describes why this happens?

• Some closely packed particles at the surface of the liquid break the bonds which are keeping them close to neighbouring particles.

• Breaking bonds is an endothermic process (requires energy).

• When particles enter the gaseous state they take their (kinetic) energy with them.

• Particles at the surface of the liquid make bonds with gaseous particles above the surface of the liquid.

• Making bonds is an exothermic process (releases energy).

• Liquid B boils at 30°C

• Liquid C boils at 40°C

• Liquid D boils at 50°C

• They have no fixed shape and no fixed volume.

The three states of matter are represented by diagrams X, Y and Z. Which change occurs during condensation?
