Boyle's Gas
Paden Hurst & Scott Rogers
Equation
P1 x V1 = P2 x V2
Definition
For a fixed mass of gas at constant temperature the volume of the varies inversely with pressure.
His Experiment!
Robert Boyle employed a J-shaped piece of glass tubing that was sealed on one end. A gas (air) was trapped in the sealed end of the tube and varying amounts of mercury were added to the J-shaped tube to vary the pressure of the system. Boyle systematically varied the pressure and measured the volume of the gas. These measurements were performed using a fixed amount of gas and a constant temperature. In this way Boyle was able to examine the pressure-volume relationship without complications from other factors such as changes in temperature or amount of gas.
