1.Why are there two different values for R?(R = 8.314472JK-1mol-1 = 0.0820574 L atm K-1mol-1
2.Why are liquid barometers filled with mercuryrather than water?
3. Using the concepts of the kinetic theory of gases, describeWHY one gas will diffuse through another.
4. Why does hot air rise? Prove your answer using the ideal gasequation
5. Why do gases show a positive deviation from ideal behaviourat high pressures? (i.e Why don’t they only show negativedeviations?)
