Answer 2

Condensing

Question 3

What is the process of water to ice ?

Answer 3

Freezing

Question 4

What state of led would it be in if it’s put in the oven?

Answer 4

It would be a solid and wouldn’t melt because it’s melting point is really high

Question 5

What are the three states of matter?

Answer 5

Sold liquid and gases

Question 6

The particles are in - positions. Solids can not be - . Solids have fixed -.

Answer 6

Fixed compressed volumes

Question 7

The particles can move - one another but cannot -. Liquids have fixed volume but can be -.

Answer 7

Past escape poured

Question 8

What is it if the particle diagram is irregular?

Answer 8

Liquid

Question 9

What is gas pressure?

Answer 9

It’s when the particles are vibrating and colliding into each other and the walls of the container

Question 10

Would adding more air into a container increase the pressure or decrease it?

Answer 10

It increases the pressure because adding more particles cause more frequent collisions into the walls

Question 11

Is it the higher the pressure the higher temp?

Answer 11

Yes

Question 12

At what temperature does water boil

Answer 12

100 ‘c

Question 13

Solid - liquid - gas - liquid - solid

Answer 13

Melting evaporating condensing freezing

Question 14

What can’t you do with a solid?

Answer 14

You can’t compress a substance or make it flow

Question 15

What can’t you do with a liquid?

Answer 15

You can’t compress a substance but you can make it flow

Question 16

What can you do with a gas that you can’t do with a solid and liquid?

Answer 16

You can compress a substance and make it flow

Question 17

What is the difference between evaporating and boiling?

Answer 17

Boiling: it can only happen at the boiling point (100’c)

Evaporation: it can happen at any temperature

Question 18

How can a liquid Change into gas ?

Answer 18

By evaporating or boiling

Question 19

What temperature does water boil at ?

Answer 19

100’c

Question 20

Why when you take a bottle full of air (that has caved in) out of the freezer does it pop out?

Answer 20

Because when you take it out (warms up) the particles vibrate more and it crashes into the wall more so it causes more gas pressure

Question 21

What is it called when a solid goes straight into gas?

Answer 21

Subliming

Question 22

What causes gas pressure?

Answer 22

Gas particles colliding with the walls and each other exert on pressure on the container

Question 23

Does adding more air increase the pressure?

Answer 23

Yes because adding more particles cause more frequent collisions into the walls

Question 24

Think in you head what a graph looks like and how you would do it

Answer 24

Have you done it ,good

Question 25

When the water boils do the particles stay together?

Answer 25

The particles stay together but when it starts to boil the particles move away from each other

Question 26

Do particles stay the same size when they boil?

Answer 26

Yes they do
