1 a) States of Matter

Question 1

Diffusion

Answer 1

Random movement of particles from a high concentration to a low concentration.

Question 2

Saturated Solution

Answer 2

A solution that contains as much dissolved solid as possible at a particular temperature.

Question 3

Solubility

Answer 3

The mass of solute which must dissolve in 100g of solvent to form a saturated solution at a particular temperature.

Question 4

Boiling

Answer 4

Liquid to a gas

Question 5

Condensation

Answer 5

Gas to a liquid

Question 6

Deposition

Answer 6

Gas to a solid

Question 7

Dilute (dilution)

Answer 7

Added water to make a solution weaker

Question 8

Evaporation

Answer 8

Liquid to a gas at a temperature below the boiling point from the surface of the liquid only.

Question 9

Freezing

Answer 9

Liquid to a solid

Question 10

Insoluble

Answer 10

Does not dissolve in a particular solvent

Question 11

Melting point

Answer 11

The temperature at which a substance changes its state from a solid to a liquid. Pure substances have a fixed melting point but a mixture may melt over a range of temperatures.

Question 12

Solubility Curve

Answer 12

Graph showing how the solubility of a solute changes with temperature.

Question 13

Solute

Answer 13

Substance that dissolves

Question 14

Solution

Answer 14

Mixture formed when a solute dissolves in a solvent

Question 15

Solvent

Answer 15

Liquid that a solute dissolves in

Question 16

Sublimation

Answer 16

Solid to a gas
