Explain how gasses exert pressure on the inside of a container:
Gas pressure is due to particles hitting the surface
1 of 7
What happens to the pressure of a gas if the temperature of the gas is increased?
Increasing the temperature increases pressure, because they hit the walls harder and faster
2 of 7
What happens to the pressure of a gas if the volume of the gas is decreased?
Reducing the volume increases the pressure because the gas hits the walls more often

Write the two rules for naming compounds:
1. When two different elements combine the ending is usually '-ide'. 2. When three or more different elements combine- and one of them is oxygen- the ending will usually be '-ate'

List four mixture separation techniques, with an example for each one:
1. Filtration e.g. separating rock salt. 2. Evaporation e.g. separating rock salt. 3. Chromatography e.g. separating dyes in inks. 4. Distillation e.g. separating mixed liquids
