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.
