Name Equation Definition Force Mass x gravity (kg.m/s 2 ) Force produced by an object is due to mass and gravity. On earth gravity = 9.81m/s 2 Pressure P = force/area (kg/m.s 2 ) Force applied to unit of area. Boyles Law P 1 V 1 =P 2 V 2 Since pressure is inversely related to volume, the product of P and V will always be a constant when temp. is constant. Charles Law V 1 /T 1 = V 2 /T 2 Since volume and Kelvin temperature of a gas are directly proportional, the quotient of V/T is always a constant when pressure is constant. Gay- Lussac’s Law P 1 /T 1 = P 2 /T 2 Pressure is directly proportional to Kelvin temperature , the quotient of P/T is constant when volume is constant. Combined Gas Law P 1 V 1 / T 1 =P 2 V 2 / T 2 Using the three equations above, we can express these ideas together in the combined gas law. A very useful law in the lab since we are rarely at STP!! Avo gadro’s Law V 1 /N 1 = V 2 /N 2 Volume of a gas is directly proportional to number of moles, this holds true for
