Question

real gas deviate from ideal gas behaviour. how? ​

Answer 1

Answer:

While the particles of an ideal gas are assumed to occupy no volume and experience no interparticle of a real gas do have finite volumes and do attract one another. As a result real gasses are often observed to deviate from ideal behaviour

Answer 2

There are two notable situations in which the behavior of real gases deviates from that model:
