Question 1

What are the 3 states of matter? EASY QUESTION

Answer 1

Solid
Liquid
Gas

Question 2

What is the term for when a gas becomes a liquid? When does this happen?

Answer 2

Condensation happens at the boiling point.

Question 3

What is the term for when a solid becomes a liquid? When does this happen?

Answer 3

Melting happens at the melting point.

Question 4

What is the term for when a liquid becomes a solid? When does this happen?

Answer 4

Freezing happens at the melting point.

Question 5

What is the term for when a liquid becomes a gas? When does this happen?

Answer 5

Boiling happens at the boiling point.

Question 6

What is the term for when a solid becomes a gas? When does this happen?

Answer 6

Sublimation

Question 7

Why can gasses be squashed easily?

Answer 7

Because there is space between the particles.

Question 8

Why are forces between particles overcome when heated?

Answer 8

Because there is more energy to help overcome the forces.

Question 9

What is a solvent?

Answer 9

A solvent is a substance (usually a liquid) that something else dissolves in.

Question 10

What is a saturated solution?

Answer 10

When no more of the solute can dissolve in the solvent.

Question 11

What is diffusion?

Answer 11

The movement of particles from high to low pressure.

Question 12

Name 5 differences between evaporation and boiling.

Answer 12

1. Boing only occurs at the boiling point but evaporation happens at many temperatures (between the melting and boing points).
2. Boiling happens throughout the liquid, however, evaporation only happens on the surface.
3. Boiling happens quickly but evaporation is slower.
4. when a liquid boils the temperature stays constant but evaporation causes cooling.
5. when a liquid boils the whole liquid becomes a gas, but only some particles become gas particles on evaporation.
