Answer 1

Melting

Question 2

Change of state from liquid to gas is called

Answer 2

Boiling

Question 3

Change of state from gas to liquid is called

Answer 3

Condensing

Question 4

Change of state from liquid to solid is called

Answer 4

Freezing

Question 5

Change of state from solid directly to gas is called

Answer 5

Sublimation

Question 6

What is the kinetic theory

Answer 6

Is the theory that

• All matters are made up of very tine particles
• The particles’ arrangements are different at 3 states (solid, liquid, gas).

Question 7

How do the particles behave when in a solid state according to the kinetic theory?

Answer 7

• They don’t move, just vibrating in place
• Arranged in a lattice shape
• Have a fixed volume and shape

Question 8

How do the particles behave when in a liquid state according to the kinetic theory?

Answer 8

• Particles can move past each other
• Have a fixed volume but no fixed shape
• Can flow and fill up the container that contains them

Question 9

How do the particles behave when in a gas state according to the kinetic theory?

Answer 9

• Particles can move freely and are far apart from each other
• No fixed volume, no fixed shape
• Can flow and fill up the container that contains them.

Question 10

According to the kinetic theory, say out the states in order from lowest energy to highest energy.

Answer 10

Solid, Liquid, Gas.
