what is the difference between real gas and ideal gas?

OpenStudy (anonymous):

Ideal gas follow the perfect gas law, while real gas usually don't. Ideal gas ignore the attraction and repulsion between gas molecules, if we want to use perfect gas law to describe real gas, there must be some revision terms. We usually use Van de Waals equation to decribe real gas(though the perfect gas law is useful enough in experiment ^^).

so,it means that real gas has attraction and repulsion right??is that the only thing that differ from ideal gas??

OpenStudy (unklerhaukus):

a real gas has particles of finite size, these take up non-negligible volume when the gas is compressed

OpenStudy (anonymous):

while real gas such as O2, N2, NH3...etc are more complicate than the describing above ^^
