E - States of Matter - Paper 2

Question 1

Give an example of Brownian motion.

Answer 1

Smoke particles in airPollen in waterDust particles in air

Question 2

Explain how Brownian motion supports the idea that matter is made from tiny particles in continuous motion.

Answer 2

In Brownian motion particles can be seen moving in a random way. This is because larger visible particles are bumping into very tiny particles.

Question 3

How do particles in a solid move?

Answer 3

Particles vibrate about a fixed position.

Question 4

How do particles in a liquid move?

Answer 4

Particles can move and slide past each other.

Question 5

How do particles in a gas move?

Answer 5

Particles are able to move freely at different speeds in a random motion.

Question 6

How are particles in a solid arranged?

Answer 6

Particles are closely packed and arranged in a regular pattern.

Question 7

How are particles in a liquid arranged?

Answer 7

Particles are arranged in an irregular way but with little space between particles.

Question 8

How are particles in a gas arranged?

Answer 8

Particles are randomly postioned and far apart from each other.
