when we plot graph against P and PV, at 17¡ãC,:
for H2, there's straight ascending line.
for N2, line a little curved at low P then become ascending straight like H2.
for CO2, line curved, very descending at low P, then ascend but don't reach the ideal line.
please can you explain this in terms of P, V, T and inter molecular forces?
