Question

Real gases do not follow gas laws perfectly under all conditions. Why?

Answer 1

An ideal gas is composed of randomly moving minute particles, which undergo elastic collisions. Real gases are the ones which do not follow the ideal relations of gas law. The deviation of real gas from ideal gas behavior occurs due to the assumption that, if pressure increases the volume decreases. The volume will approach a smaller number but will not be zero because the molecules will occupy some space that cannot be compressed further.
