The ideal gas laws and equations are true for all gases at
low pressures and lower temperatures
low temperatures and high pressures
high pressures and high temperatures
low pressure and high temperatures
Correct answer is D
At high temperature and low pressure, the vanderwaal equation is reduced to ideal gas equation.
i.e, [P + av2] [v - b] = RT is reduced to PV = nRT
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure as the potential energy due to intermolecular forces, it becomes less significant compared with the particles kinetic energy and the size of the molecules, then it becomes less significant compared to the empty space between them.
