Why do gases deviate from ideal gas behaviour?
UNO [17]

The ideal gas behavior gets deviated because of the real gases. The particles in the gas occupy finite space and exert interactive forces between themselves.  

Explanation:

An ideal gas behavior is at low temperature and at high pressure. According to kinetic theory, the ideal gases "do not occupy space" and there is "no interaction" among the gas molecules. But practically while applying the gas laws this is not the actual case.

<u>Ideal gas equation: </u>

PV = nRT
