The ideal gas laws and equations are true for all gases at?

A. low pressures and lower temperatures
B. low temperatures and high pressures
C. high pressures and high temperatures
D. low pressure and high temperatures

Correct Answer:

Option D – low pressure and high temperatures

Explanation

At high temperature and low pressure, the van der waal equation is reduced to ideal gas equation.

i.e, [P + a/v²] [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.
