Q

In which state/s of matter are the particles moving?

Describe the movement of the partcles

A

Solids: The particles are vibrating

Liquids: The particles are moving around each other

Gases: the particles can move in any direction

Q

Which states of matter can be compressed (squashed to fill a smaller volume)?

A

Gases

Solids and liquids cannot be compressed as the particles are already touching each other.

Q

Which states of matter have a fixed density?

Fixed means it cannot be changed

A

Solids and liquids because they can’t be compressed. The particles are already touching each other.

17
Q

Condensation is when…

A

A gas changes to a liquid

18
Q

Sublimation is when…

A

A solid changes to a gas

19
Q

If you freeze 1 kg of water, what will happen to its mass?

A

The mass wil stay the same: you will have 1 kg of ice

Because changing state does not change mass.

20
Q

If you boil 1 kg of water, what will happen to its mass?

Explain your answer

A

The mass wil stay the same: you will have 1 kg of steam

Because changing state does not change mass.
