Ch1 Kinetic Theory And Diffusion

Question 1

What is it called when a liquid turns to a solid and what happens?

Answer 1

Freezing

Particles slow down enough that forces return

Question 2

What is it called when a liquid turns to a gas and what happens?

Answer 2

Boiling

Particles move fast enough to break all the forces of attraction

Question 3

What happens when a gas turns to liquid and what happens?

Answer 3

Condensing

Particle slowdown and forces return

Question 4

What is it called when a solid turns to a gas?

Answer 4

Sublimation

Question 5

In showing that the particles in different gases travel at different speeds, what correlation do we find between light and heavy particles?

Answer 5

Light particles travel faster then heavier particles

Question 6

What is it called when a solid turns to liquid and what happens?

Answer 6

Melting

The particles need to vibrate fast enough that the forces attractions break (melting point)
