why hydrogen is not an ideal gas?
Answers
Answer:
Hydrogen gas properties can be predicted fairly accurately using the IDEAL GAS equation PV=nRT because it has very low intermolecular forces and the molecules are very small. BUT, an IDEAL gas has zero intermolecular forces and zero molecular volume so Hydrogen is not an ideal gas. ... Remember NOTHING IS an ideal gas
Answer:
An Ideal gas is a figment It is imaginary. No real gas even under the conditions when it obeys the ideal gas law has the "properties of an ideal gas".[Even an ideal gas properties are defined further by the kinetic theory of gases]
H2 is diatomic so energy is stored in translation and rotational and vibrational states so this complicates things a bit since ideal gases don't do that, so helium being monatomic is closest to ideal behavior. The ideal gas law is best considered as a limiting law as the size of molecules and intermolecular forces between molecules approach zero. For real gases they only appear to get close at reasonably low pressures and reasonably high temperatures.
