the spreading out of particles to fill the space that they are in

Question 11

Melting

Answer 11

Solid into a liquid

Question 12

Boiling

Answer 12

Liquid to a gas

Question 13

Physical change

Answer 13

No new substance is formed, there is no change in mass and the reraction can be easily reversed

Question 14

Melting point

Answer 14

The temperature at which a substance changes from a solid to a liquid, melting point of ice is 0OC

Question 15

Freezing

Answer 15

The temperature at which a liquid changes to a solid

Question 16

Evaporation

Answer 16

When the particles of a liquid gain so much energy they leave the surface and form a gas

Question 17

Boiling point

Answer 17

The temperature at which a liquid becomes a gas

Question 18

Condensation

Answer 18

Cooling a gas takes its energy, making the particles move closer and become a liquid

Question 19

Sublimation

Answer 19

When some substances are heated, they do not become a liquid, they become a gas straight away.
