U1 Kinetic Theory

Question 1

Solids

Answer 1

Particles are very close to one another.
Particles vibrate on the spot.
object has fixed shape and volume.
Particles are are lowest energy state.

Question 2

Liquids

Answer 2

Particles close together.
Particles move around randomly.
object has a fixed volume but takes the shape of its container.
Particles are at high(ish) level of energy.

Question 3

Gases

Answer 3

Particles far apart.
Particles move randomly and very quickly.
Gases fill the space they are in a they have no fixed volume.
Particles are at highest level of energy

Question 4

what happens when a solid is heated?

Answer 4

The particles gain energy and vibrate on the spot more. Then the solid expands and turns into a liquid.
