as temperature increases pressure increases
directly proportional

1 of 13

Charles' Law

as temperature increases the volume of a gas increases
directly proportional

2 of 13

Boyle's Law

as volume increases the pressure decreases
inversely proportional

3 of 13

Fossil fuels

a non-renewable resource, energy is released through combustion reactions

4 of 13

Combined Gas Law

links temperature, pressure and volume

5 of 13

Ideal Gas equation

PV=nRT
combines Pressure, volume, temperature and the number of moles. R is the universal gas constant.

6 of 13

saturated solution

A solution in which no more solute can be dissolved in the solvent without increasing the temperature.

7 of 13

Thin Layer Chromatography

Stationary phase of silica or alumina on a glass plate. Mobile phase - a liquid. The mobile phase flows through the stationary phase and carries the components of the mixture with it. Different components travel at different rates due to polarity of the t

8 of 13

number of moles

n=mass (g)/Molar Mass

9 of 13

concentration

c=number of moles/volume (L)

10 of 13

concentrated

a solution with a relatively large proportion of solute in the solvent

11 of 13

dilute

a solution with a relatively small proportion of solute in the solvent

12 of 13

AAS

Atomic absorption spectroscopy - is a technique for measuring the concentrations of metallic elements in different solutions.
