1. Boyle’s Gas Law
** At constant temperature and
quantity of gas the Ideal Gas Law =
PV = nRT    →    P x V = k (constant)
Under changing P or V Boyle’s law is:
P1V1 = P2V2

2. Boyle’s law is the inverse relationship between the pressure and volume of a gas.

6. Dalton’s Law of Partial Pressure
In a mixture of two or more
gases, each gas behaves just as
if it were the only one in the
container, exerting a pressure
called its partial pressure. 
The total pressure in a mixture
of gases is equal to the sum of each individual gases partial pressure. 
PTotal  = P1 + P2 +  P3…..
Total Pressure = Pressure (gas 1) + Pressure (gas 2) + ..
