Boyle's Law
Boyle’s law relates these two variables that effect gases.
What is Volume and pressure?
V1 = 215 mL
T1 = 300 K
T2 = 225 K
Solve for V2
161.25 mL
This is held constant in Gay-Lussac's law
What is volume.
A sample of nitrogen occupies a volume of 250 mL at 25 c. what volume will it occupy at 95 c.
What is 308.7 mL
A football inflated inside and then taken outdoors on a winter day shrinks slightly.
Charle's Law

What is 423L
V1 = 3.5 L
T1 = 273 K
V2 = 5.0 L
Solve for T2
390 K

T1 = 200 K
T2 = 300 K
Solve for P2
1110 mmHg
The relationships between the following four variables are known as the gas laws.
Pressure, Temperature, Volume and Moles
A slightly under inflated rubber life raft left in bright sunlight swells up (Why shouldn't you overinflate your life raft when your ship goes down in tropical waters?)
Charles law
A sample of neon occupies a volume of 461 mL at STP (273 K & 1 atm). What will be the volume of the neon when the pressure is reduced to 0.92 atm?
