Answer 3

1. material 2. temperature 3. pressure

Question 4

Can you identify 5 properties of substances?

Answer 4

1. volume 2. shape 3. density 4. compressibility 5. ease of flow

Question 5

Can you identify 5 properties of solids

Answer 5

1. definite volume 2. definite shape 3. high density 4. no compressibility 5. no ease of flow

Question 6

Can you identify 5 properties of liquids

Answer 6

1. definite volume 2. match the shape of the bottom of the container 3. medium density 4. no compressibility 5. flow easily

Question 7

Can you identify 5 properties of gases

Answer 7

1. no definite volume - fill the container 2. shape same as the container 3. low density 4. easily squashed 5. flow easily

Question 8

The particles in a substance stay the same whether it is a …

Answer 8

soild, liquid or gas

Question 9

What changes in the different states?

Answer 9

1. particles energy 2. arrangement of the particles

Question 10

Energy - solids, liquids and gases

Answer 10

solids - least energy liquids - medium energy gases - most energy

Question 11

attraction - solids, liquids and gases

Answer 11

solids - strong liquids - medium gases - weak

Question 12

Solids - position arrangement vibrate movement

Answer 12

1. fixed position 2. regular arrangement 3. vibrate - yes 4. movement - no

Question 13

In which state particles are closely packed together?

Answer 13

solids

Question 14

In which state there are lots of particles in a small volume?

Answer 14

solids

Question 15

Are the particles constantly moving in a liquid?

Answer 15

yes

Question 16

Why gases have low density?

Answer 16

because there are few particles in a large volume

Question 17

In which state particles move alot in all directions?

Answer 17

gas

Question 18

Why is there gas pressure in a container?

Answer 18

because particles are hitting a surface with force

Question 19

When you increase the temperature, what happens to the particles in a gas?

Answer 19

the particles gain more energy and move faster

Question 20

When you increase the temperature, what happens to the pressure of the container? Why?

Answer 20

The pressure will increase because the particles will hit the walls harder and more often

Question 21

What happens when you reduce the volume of the container with a gas inside? What will happen to the pressure?

Answer 21

The pressure will increase because the particles are squashed up in a smaller space, so they will hit the walls more often

Question 22

Define diffusion

Answer 22

Diffusion is particles moving from higher concentration to lower concentration.

Question 23

Why is smell diffusion slow?

Answer 23

Diffusion is slow because the smell particles keep bumping into air particles. which stops them making forward progress and often sends them off in a completely different direction.

Question 24

What is particle theory?

Answer 24

The particles in a substance stays the same whether it’s a solid, a liquid or a gas. What changes is the arrangement of the particles and their energy.
