Boyle's law states that:
Given a constant temperature and pressure, increasing the molecules in a container will increase the pressure.
given a volume of gas, increasing the pressure on the gas will increase the number of molecules in the gas.
Given a gas of constant temperature, if you increase the volume of the chamber in which the gas is contained, pressure will decrease.
None of the above
