high

Question 19

shape of gas? (definite or indefinite?)

Answer 19

indefinite

Question 20

volume of gas?(definite or indefinite?)

Answer 20

indefinite

Question 21

can gas be compressed?

Answer 21

yes

Question 22

process from solid to liquid?

Answer 22

melting

Question 23

process from liquid to gas?

Answer 23

boiling/evaporation

Question 24

process from gas to liquid?

Answer 24

condensation

Question 25

process from liquid to solid?

Answer 25

freezing

Question 26

process from gas to solid?

Answer 26

vapour deposition

Question 27

process from solid to gas?

Answer 27

sublimation

Question 28

what is sublimation?

Answer 28

Sublimation is when a solid changes straight into a gas without becoming a liquid first. The solid gains energy from the surroundings, making the surroundings cooler while the solid becomes a gas.

Question 29

what is vapour deposition?

Answer 29

It happens when gas particles cool down, slow down, and stick together to form a solid. During this, energy is given to the surroundings, making the surroundings warmer while the gas becomes a solid.
