Boyle’s Law Pressure and volume are inversely related (constant T , temperature, and n , # of moles of gas) PV = k ( k is a constant for a given sample of air at a specific T) 11 2 2 = PV PV × ×

Boyle’s Law Example 2. A sample of helium gas occupies 12.4 L at 23°C and 0.956 atm. What volume will it occupy at 1.20 atm assuming that the temperature stays constant?
