Matter: Its Properties and Changes

The change of state from gas to liquid is called:

• evaporation

• condensation

• fusion

A substance is crystallized when it passes from:

• liquid to solid without being a gas.

• solid to gas without being a liquid.

• gas to solid without being a liquid.

The temperature in which a solid converts into liquid is called:

• fusion point

• boiling point

• freezing point

The change from liquid to gas is called:

• fusion

• evaporation

• condensation

The process by which a liquid changes into a solid state is:

• crystallization

• solidification

• combustion

A material that is combined with oxygen goes through:

• combustion

• oxidation

• sublimation

The change from solid to gas without being a liquid is called:

• crystallization

• sublimation

• evaporation

The changes of state in which the matter absorbs heat are:

• fusion and sublimation

• fusion and condensation

• evaporation and solidification

Effervescence and heat release are clues of a:

• change of state

• chemical change

• physical change

The chemical change in which a material is burnt is known as:

• combustion

• oxidation

• evaporation
