When is deviation more in the behaviour of a gas from the ideal gas equation $$PV= nRT$$?

AAt high temperature and low pressure
BAt low temperature and high pressure
Correct Answer
CAt high temperature and high pressure
DAt low temperature and low pressure

Solution

An ideal gas is defined to be a system in which there are no intermolecular/interatomic forces. Such a system can only exist as a gas. Any real system will approach ideal gas behaviour in the limit that the pressure is extremely low and the temperature is high enough to overcome attractive intermolecular forces.
PV = nRT
here, n= no of moles of gas
Ideal gas equation is a relation between four variables and it describes the state of any gas. For this reason, it is also called Equation of State.
At low temperature and high pressure, gases deviate more from ideal condition.
because as pressure increases, force of attraction increases and molecules become closer.
