real life vs. ideal

Postby mehaksk » Sun Mar 10, 2024 1:24 pm

Can someone explain to me what assumptions are made about the particles in an ideal gas, and how do these assumptions fail to describe real gases under certain conditions?

In an ideal gas, particles are assumed to have negligible volume, experience no intermolecular forces, and undergo perfectly elastic collisions. However, these assumptions fall short of natural gases at high pressures or low temperatures. At such conditions, natural gases deviate from ideal behavior due to particle volume becoming significant and intermolecular forces impacting their behavior, resulting in deviations from perfect gas laws.

The volume is so minuscule it's not important to note and there are no intermolecular forces for particles in an ideal gas. However, for real gasses, if there is a high temperature or low pressure, volume and intermolecular forces change.
