Solution: The graph shows PV/RT for carbon dioxide at three different temperatures.Rank the curves in order of increasing temperature.

Problem

The graph shows PV/RT for carbon dioxide at three different temperatures.

Rank the curves in order of increasing temperature.

The figure shows PV divided by RT as a function of pressure. The PV divided by RT is measured from 0 to 2 on the y-axis, while the pressure is measured from 0 to 1200 atmospheres on the x-axis. There are three curves on the diagram. The curve A of the plot goes down from 0.85 at 0 atmospheres, passes through the minimum at 0.5 at 100 atmospheres, and then rises to 1.9 at 950 atmospheres. The curve B of the plot goes down from 0.9 at 0 atmospheres, passes through the minimum at 0.6 at 200 atmospheres, and then rises to 1.4 at 950 atmospheres. The curve C of the plot goes down from 1 at 0 atmospheres, passes through the minimum at 0.6 at 200 atmospheres, and then rises to 1.1 at 950 atmospheres.


Solution

For an ideal gas: PV/RT = 1 at any Pressure.

Gases exhibit ideal behavior at relatively high temperatures and low pressures.
