The Gas Laws Four variables are usually sufficient to define the state (i.e. condition) of a gas: Temperature, T Pressure, P Volume, V Quantity of matter, usually the number of moles, n The equations that express the relationships among P, T, V and n are known as the gas laws The Pressure-Volume Relationship: Boyle's Law Robert Boyle (1627-1691) Studied the relationship between the pressure exerted on a gas and the resulting volume of the gas. He utilized a simple 'J' shaped tube and used mercury to apply

Unformatted text preview: pressure to a gas: He found that the volume of a gas decreased as the pressure was increased Doubling the pressure caused the gas to decrease to one-half its original volume Boyle's Law: The volume of a fixed quantity of gas maintained at constant temperature is inversely proportional to the pressure The value of the constant depends on the temperature and the amount of gas in the sample A plot of V vs. 1/P will give a straight line with slope = constant...
