A substance which is gaseous under normal conditions is enclosed
in a variable volume and the variation of pressure with the volume
is recorded at different temperatures. The critical point is
determined graphically from a plot of the isotherms.
- Visualization of the critical point
- Measure a number of p-V isotherms of ethane.
- Determine the critical point and the critical quantities of
- Calculate the constants of the Van der Waals equation, the
Boyle temperature, the radius of the molecules and the parameters
of the interaction potential.
