The state change name for a solid changing to a liquid

Melting

200
What happens to particles when they are cooled?
They move slower.
200
Draw the particle arrangement of a solid.
Particles should be close together in a fixed shape.
200
Draw the particle arrangement of a liquid.
Particles should be slowly rolling over each other, but not taking up the whole space.
200
Draw the particle arrangement of a gas.
Answer should have particles completely spread out and arrows showing fast movement.

What happens to a liquid when it EVAPORATES?

Turns into a gas (water vapour).

TRUE or FALSE 'Particles in gases are closer together than particles in solids'

FALSE

300

When a gas turns into solid directly without going through a liquid state

Deposition

400
Why do solids, liquids and gases have different properties?
The particles are arranged differently.
400

TRUE or FALSE 'The particles in a solid stay completely still'
FALSE They vibrate on the spot.
500
TRUE or FALSE 'Liquid particles will spread out to fill the entire space of a room'
