The ideal gas law describes the relationship among the pressure P, volume V, number of moles n., and absolute temperature T of an ideal gas. Here is the relationship expressed mathematically: PV = nRT where R is a proportionality constant. The units of R are determined by the units of pressure and volume used in the equation.

Question

Transcribed Image Text:The ideal gas law describes the relationship among the pressure P, volume V,
number of moles n, and absolute temperature T of an ideal gas. Here is the
relationship expressed mathematically:
PV = nRT
where R is a proportionality constant. The units of R are determined by the
units of pressure and volume used in the equation. When bar used for
pressure and L for volume, the appropriate R value is
0.08314 L bar mol-¹ K-¹.
Part A
