Thermal equation of state and critical point
Principle: 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.
Tasks:
1. Measure a number of p-V-isotherms of ethane.
2. Determine the critical point and the critical quantities of ethane.
3. Calculate the constants of the Van der WAALS equation, the BOYLE-temperature, the radius of the molecules and the parameters of the interaction potential.
