Boyles Law
At constant temperature, pressure and volume have an inverse relationship
Boyles Law Formula
P1V1 = P2V2
P
Pressure of the gas
V
Volume of the gas

T1 T2
Combined Gas Relationship
Nothing is constant
A 10 mL sample of gas is at a Pressure of 700 mmHg. A student wants the volume of the gas to be 110 mL. At what pressure does the student need to be at to achieve this volume?
63.63 mmHg = 64 mmHg
A 25 mL sample of gas was heated from 30C to 150C. What is the new volume of the sample at this temperature?
V2 = 34.89 = 35 mL
A gas in an aerosol can is at a pressure of 3.5 atm and 25oC. Directions on the can warn users not to keep the can in a place where the temperature exceeds 55oC. What would the pressure of the gas in the can be at 55oC?
P2 = 3.85 atm = 3.9 atm
A student is studying a 35 mL sample of gas at 25oC and 1.5 atm. What would the new volume of the gas be if the sample conditions changed to 105oC and 0.5 atm?
V2 = 133.17 mL = 133 mL
A student is working with 450 mL of Ne gas at STP. What would the volume of the gas be if the gas was exerted to 125oC and 50 kPa?
V2 = 1328.9 mL = 1329 mL
A 150 mL sample of Kr gas is being held at a temperature of 200K and a pressure of 2.5 atm. What would the new volume of gas be at STP?
V2 = 512.16 mL = 512 mL
6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume is 3.5 L. What is the new pressure inside the piston?
P2 = 1.7 atm
A weather balloon has a volume of 35 L at sea level (1.0 atm). After the balloon is released it rises to where the air pressure is 98.5 kPa. What will the new volume of the weather balloon be?
V2 = 35.999 = 36 L
CaCO3 decomposes at 12000C to form CO2 gas and CaO. If 25 L of CO2 are collected at 12000C, what will the volume of this has be after it cools to 250C.
V2 = 1.1 L
A student has.a 450 mL sample of gas 1.5 atm and 75C in a sealed container. What volume would the gas contain if it were increased to 205C and the pressure decreased to 0.25 atm?
V2 = 3708 mL
