At high temperatures and low pressures, yes. Real molecules depart from the ideal gas law at high pressures and low temperatures.

High and low are relative terms, meaning a low temp for one substance may be a high temp for another substance.

Avogadro's Law states that a constant, 6.022 x 1023, molecules of any gas is present in a volume of 22.41 liters. This law applies to all gases.

Would a gas whose molecules were true geometric points obey the ideal gas law?

If gas molecules were true geometric points (ie had zero volume) AND had zero intermolecular interaction (such as attraction or repulsion), then the gas would obey the ideal gas law. Gases composed of small, non-interactive molecules (such as helium gas) obey the ideal gas law pretty well (as long as the gas is low density and temperature is rather high). For non-ideal gases, at least two correction factors are often used to modify the ideal gas law (correcting for non-zero volume of gas molecule and intermolecular attraction) such as in the Van der Waals equation for a real gas.


Why Real gases do not obey gas laws?

Real gases do not obey gas laws because these gases contains forces of attractions among the molecules..and the gases which do not contain forces of attraction among their molecules are called ideal gases and they obey gas laws.


How does the ideal gas law relate to real gases?

Ideal gas law states that there are no inter molecular attractions between gas molecules and that ideal gas does not occupy space therefore having no volume. However, a real gas does have intermolecular attractions and does have a volume.


Why do gases failed to obey ideal gas equation at high temperature and low pressure?

You have the idea backwards, gases fail to obey the ideal gas laws at low temperatures and high pressures. The ideal gas law assumes the size of a gas molecule to be negligible as well as the naturally occurring attractive forces between molecules in a gas. These difference diminish when the pressure is low or the temperature is high. Low gas pressure suggests the gas molecules are fairly spaced out, so their individual volumes aren't impeeding the other molecules ability to occupy nearby space. With high pressures gas molecules are forced closer together in order to fit the same amount of volume the greater the volume of individual molecules the less volume available fore gas molecules to occupy. Similarly with high temperatures, the average kinetic energy easily overwhelms the intramolecular forces such as london forces and hydrogen bonding, making their presence almost unimportant. In low temperature applications the imfs of the gas molecules are given much more opportunity to interact as the gas molecules have significantly less kinetic energy.

What is the name of law given to number of molecule is inversely proportional to pressure?

There is no such law. The Ideal Gas Law states that pressure is proportional to the number of molecules Pressure x Volume = number x Ideal gas constant x Temperature


Why real gases deaviat from ideal behaviou?

It is assumed that Ideal Gases have negligible intermolecular forces and that the molecules' actualphysical volume is negligible. Real Gases have the molecules closer together so that intermolecular forces and molecules' physical volumes are no longer negligible. High pressures and low temperatures tend to produce deviation from Ideal Gas Law and Ideal Gas behavior.


How did the ideal gas law contribute to the gas law?

All gas laws are absolutely accurate only for an ideal gas.

What substance does the ideal gas law apply to?

Anything basically in the gas state...however no gas ever truly follows the ideal gas law, as it fails to consider a molecules attraction to other molecules as well as the actual space each molecule takes up. However these difference are minute and only usually noticed at extremely high pressures and really low temperatures. molecular interactions become unimportant with increasing temperatures as their kinetic energy doesn't allow them to easily interact. The volume of the gas molecule becomes unimportant when the pressure is low, because the average distance between the gas molecules becomes much greater than the size of the molecule. These differences are accounted for in the modified ideal gas law

What would the volume and pressure of an ideal gas be at absolute zero temperature IF an ideal gas actually existed?

Here's the ideal gas law: PV = nRT If T is zero, then PV must be zero; assuming the volume is nonzero, then for PV to be zero the pressure must be zero. However, this is only true for an ideal gas. For a real gas other factors come into play at low temperatures, and they begin to deviate from the ideal gas law. Also, all real gases liquify above absolute zero, and liquids don't obey the ideal gas law at all.
