When real gases obey the ideal gas equation PV=RT
Answers
The real gases obey the ideal gas equation PV = RT at high temperature and low pressure.
Real gases do not obey the ideal gas laws under all conditions of temperature and pressure. Gases obey the laws of Boyle, Gay-Lussac and Avogadro at low pressures and moderately high temperatures. But when the pressure is increased or the temperature is decreased there is a marked deviation from ideal behaviour.
Answer:
Explanation:The essential properties of the molecules of an ideal gas are zero volume of the molecules and mutual force between them.At low pressure the volume of a gas is large so that the volume of gas is negligible as compared to the volume of the gas.At high temperature the K.E of molecules is quite large so that effect of intermolecular forces on the motion of molecules is negligible. Hence at low pressure and high temperature, a real gas is approximately ideal. Consequently, the gas equation gives more accurate results.
