Ideal Gas Law

Ideal gases are gases in which the particles of the gas only interact through elastic collisions; there are no intermolecular forces between the particles. Real gases can approximate ideal gases at conditions of low pressure and high temperature where the intermolecular forces are negligible. Under those conditions the equation of state for an ideal gas holds: PV=nRT (1) where the pressure (P) and volume (V) are directly proportional to the temperature (T). The constant R is the universal gas constant and n is the number of moles in the volume. If V and n are held fixed and a series of measurements of pressure and temperature are made, then Eq. (1) predicts a linear relationship between the pressure and temperature. It is therefore expected that a plot of P vs. T will be a straight line with slope proportional to R. Using a regression analysis of the plot, the slope can be found, and an experimental value of R determined. Title Title
