1
Q

Diffusion

A

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

2
Q

Saturated Solution

A

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

3
Q

Solubility

A

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

4
Q

Boiling

A

Liquid to a gas

5
Q

Condensation

A

Gas to a liquid

6
Q

Deposition

A

Gas to a solid

7
Q

Dilute (dilution)

A

Added water to make a solution weaker

8
Q

Evaporation

A

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

9
Q

Freezing

A

Liquid to a solid

10
Q

Insoluble

A

Does not dissolve in a particular solvent

11
Q

Melting point

A

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.

12
Q

Solubility Curve

A

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

13
Q

Solute

A

Substance that dissolves

14
Q

Solution

A

Mixture formed when a solute dissolves in a solvent

15
Q

Solvent

A

Liquid that a solute dissolves in

16
Q

Sublimation

A

Solid to a gas
