When a sample of a gas is compressed at constant temperature from 1500 kPa to 6000 kPa, its volume changes from 76.0 cm3 to 20.5 cm3.
Which statements are possible explanations for this behaviour?
1 The gas behaves non-ideally.
2 The gas partially liquefies.
3 Gas is adsorbed on to the vessel walls.
using P1V1=P2V2; 1500x76.0 = 6000xP2
P2 = 19cm3....but the volume is 20.5 cm3 more than predicted. so the gas has slightly more volume means ideal behaviour
2 and 3 can't understand ..
