Question

True or false: nitrogen gas behaves more like an ideal gas as the temperature increases

Answer 1

Is true. Nitrogen gas behaves more like an ideal gas as the temperature increases. Under normal conditions such as normal pressure and temperature conditions , most real gases behave qualitatively as an ideal gas. Many gases such as air , nitrogen , oxygen ,hydrogen , noble gases , and some heavy gases such as carbon dioxide can be treated as ideal gases within a reasonable tolerance. Generally, the removal of ideal gas conditions tends to be lower at higher temperatures and lower density (that is at lower pressure ), since the work made by the intermolecular forces is less important compared to the kinetic energy of the particles, and the size of the molecules is less important compared to the empty space between them. The ideal gas model tends to fail at lower temperatures or at high pressures, when intermolecular forces and intermolecular size are important.
