Answer 15

Yes

Question 16

If you put a gas into 2 different beakers would it take the shape of that beaker?

Answer 16

Yes
And it would also task the volume of that beaker

Question 17

Answer 17

No

Question 18

Can a liquid be compressed?

Answer 18

No

Question 19

Can a gas be compressed?

Answer 19

Yes

Question 20

Does a solid have a fixed shape?

Answer 20

Yes
Most of the time

Question 21

Do liquid and gas have a fixed shape?

Answer 21

No they do not

Question 22

True or false substances at the temperature ABOVE, its boiling point, always gases 

Answer 22

True

Question 23

True or false substances at a temperature between its melting and boiling point, always liquid?

Answer 23

True

Question 24

True or false temperatures below, a substances melting point are always solid?

Answer 24

True

Question 25

What is diffusion?

Answer 25

It’s the movement of particles from high concentration to low concentration.

Question 26

Does down concentration require energy?

Answer 26

NO!

Question 27

Can solid particles diffuse?

Answer 27

No because they are fixed

Question 28

True or false liquid and gas particles can’t freely move
?

Answer 28

False because they can acc freely move meaning they can diffuse!

Question 29

True or false liquid and gas diffuse quicker when there’s not much kinetic energy?

Answer 29

False

Question 30

The bigger partials are heavier and will take longer to move and so diffuse.

Answer 30

Yes that is right.

Question 31

Why would a balloon pop on a hot day?

Answer 31

A balloon may pop on a very hot day because the particles of gas get hot and get energised, making them bounce off the wall, making it full and pop!

Question 32

Why would the bottle of water collapse in the freezer?

Answer 32

A bottle to water may collapse in the freezer because the particles energy (if they are the inside ones.)  This means they have no collision, but the outside particles will push the bottle walls in 

Question 33

Does a solid have a height density.

Answer 33

Yes

Question 34

What is sublimation? 

Answer 34

It’s the process from solid to gas 

Question 35

If the partial is smaller does it diffuse quicker?

Answer 35

No the bigger the partial the harder for it to defuse

Question 36

True or false when partials are colder they are smaller?

Answer 36

True
