Verified step by step guidance1
Recall that ideal gas behavior assumes negligible intermolecular forces and that gas particles occupy no volume.
Understand that at high temperatures, gas particles have more kinetic energy, which overcomes intermolecular attractions, making the gas behave more ideally.
Recognize that at low pressures, gas particles are far apart, so the volume of particles themselves and intermolecular forces have less effect, again favoring ideal behavior.
Contrast this with low temperature or high pressure conditions, where particles are closer and attractions or volume effects become significant, causing deviations from ideal gas behavior.
Conclude that real gases most closely resemble ideal gases under conditions of high temperature and low pressure.
