Question

Under which specific sets of macroscopic conditions will a typical real gas (like $O_2$ or $N_2$) exhibit behaviour that most closely approaches the predictions of the ideal gas law?

Prashant Kotian · Accepted Answer

Correct answer: A,B. A real gas approaches ideal behaviour under conditions of high temperature and low pressure. At high temperatures, the kinetic energy is large enough to overcome intermolecular attractions. At low pressures, the volume is large enough that the volume occupied by the molecules themselves is negligible.
