Question 3

What is a liquid?

Answer 3

Fixed volume, but no fixed shape.

Question 4

What is a gas?

Answer 4

No fixed shape or volume.

Question 5

What is diffusion?

Answer 5

Spreading of one substance through another, due to the movement of their particles. E.g. Iodine.

Question 6

What is matter?

Answer 6

Anything that has mass or volume.

Question 7

Melting Point?

Answer 7

Temperature at which a solid turns into a liquid (melt) or a liquid turns into a solid (freeze)

Question 8

Boiling Point?

Answer 8

Temperature liquid changes to a gas.

Question 9

Sublimation?

Answer 9

Gas to Solid or Solid to a Gas. Missing Liquid.

Question 10

Melting?

Answer 10

Solid to Liquid. Heat transferred.

Question 11

Evaporating?

Answer 11

Liquid to gas. Below 100 - Water Vapour. Above 100 - Steam.

Question 12

Freezing?

Answer 12

Liquid to Solid. Heat taken away.

Question 13

Condensation?

Answer 13

Gas with a cold surface turns into a liquid.

Question 14

Boiling?

Answer 14

Liquid to Gas.

Question 15

Precipitation?

Answer 15

Falling water in solid or liquid form. Temperature of clouds and air. Rain, hail, snow and sleet.

Question 16

Meteorologist?

Answer 16

A scientist who uses observation of the atmosphere to predict and explain the weather.

Question 17

Particle Model?

Answer 17

A description of the moving particles that make up matter.

Question 18

Particles in a solid.

Answer 18

Very close together, cannot be compressed, Attraction is strong, Fixed shape and volume, Vibrate in fixed position.

Question 19

Particles in a liquid?

Answer 19

Weak attraction and bonds, close together, can’t be compressed.

Question 20

Particles to Gas:

Answer 20

Constant motion, very weak attraction, move freely in all directions, no foxed shape or volume, large spaces between particles, able to be compressed.

Question 21

Contraction?

Answer 21

Particles move slowly, distance between particles gets smaller, attraction increases.

Question 22

Expansion?

Answer 22

Particles move faster, distance increases, attraction decreases.

Question 23

Foggy Mirrors?

Answer 23

Air cooling down becoming water.

Question 24

Invisible Gas?

Answer 24

Water vapour - hot water becomes a gas.

Question 25

Fog in the air?

Answer 25

Water vapour turns into droplets of water forming clouds.

Question 26

Foggy Mirror?

Answer 26

Water vapour transferred to cold mirror.

Question 27

Increase of particle energy = increase of temperature.

Answer 27

.

Question 28

Decrease in particle energy = decrease in temperature.

Answer 28

.

Question 29

Heated - energy added

Answer 29

.

Question 30

Cooled - energy taken away

Answer 30

.
