Question

define real gas and deviation from ideal behaviour ?​

Answer 1

The behavior of real gases usually agrees with the predictions of the ideal gas equation to within 5% at normal temperatures and pressures. At low temperatures or high pressures, real gases deviate significantly from ideal gas behavior. ... It also assumes that the force of attraction between gas molecules is zero.

Answer 2

Real gas

Gases which do not obey perfect gas love over a wide range of pressure and temperature are called real on an ideal gases. This deviations are due to interaction of molecules with each other and volume occupied by gas molecules. The repulsive forces between molecules assist expansion and attractive force assist compression.

Deviation from ideal behaviour

the curve of the real gas has a tendency to conferred with that of an ideal gas at low pressure when the volume is large. At higher pressure however definitions are observed.
