The ideal gas law effectively treats atoms as point masses that have no interactions except for collisions (no attraction or repulsion). Molecules in hot gasses generally are so far apart that their volume relative to the overall volume is insignificant. They don't attract or repel each other much either at high temperatures because they are mostly too far apart - and - they are moving so quickly that even when close, they are not close for long. As gases cool, the molecules group closer together and move slower and quit behaving in a manner that the ideal gas law can be said to represent well.

What is the properties of noble gases as a result of their stable electron configuration?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
Are molecules that have only London dispersion forces always gases at room temp?
No, molecules that primarily have only London dispersion forces are not always gases at room temperature. The physical state of a substance at room temperature depends on its molecular weight and the strength of these dispersion forces. Larger molecules with stronger dispersion forces can be liquids or solids, while smaller ones may be gases. For example, noble gases like argon are gases, while larger hydrocarbons like octane are liquids at room temperature.
Are gases at room temperature nonmetals?
Yes.
What non metals at room temp?
Most non metals are usually liquids or gases at room temperature, although not specifically one or the other. It depends on the properties of the substance. Most metals are solids at room temperature, with the exception of Mercury.
Do you freeze gas to make it a liquid?
most gases only become liquid under extreme pressure, not cold.Additional answerThere's a critical temperature, which is different for each gas, above which it won't liquefy even if compressed. Certainly a domestic freezer won't be nearly cold enough for most gases. But carbon dioxide will solidify with no compression at all.
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.
Is the boyles law is valid at high temperature?
Yes, if the pressure is low.
Halogens that are gases at room temperature and pressure?
The halogens that are gases at room temperature and pressure are fluorine and chlorine.
Which period table group are made up of only gases?
The first period or row contains only elements that are gases at standard temperature and pressure.
What is wrong if child's only symptom is a high temperature?
If a child's only symptom is a high temperature, it means you have not been looking in the right place for the cause of the high temperature.
Which substances are gases at -260 Celsius deg.?
Only helium is a gas at this temperature.
Do metals gas at room temperature?
Most metals do not gas at room temperature. They typically have high melting and boiling points, so they remain solid or liquid at room temperature. Some exceptions, such as mercury, do exist, but they are rare.
What is the Difference between airs and gases and water vapour?
Air is the mixture of different gases (like oxigen, nitrogen, co2 e.t.c.) & water vapour. Gases are only gases, here is no water vapour. And water vapour is form after the vapourization of water at high temperature.
At what temperature does a real gas obey the ideal gas laws over a wide range of pressure?
Real gases behave most like ideal gases at high temperatures and low pressures.CASE 1 :- (At Higher Temperatures)when the temperature is high the kinetic energy of molecules increases and the intermolecular attractions among the atoms decreases.The volume of the gas molecules become negligible compared to volume of the vessel. therefore the real gases act like ideal At Higher Temperatures.CASE 2 :- (At Lower Temperatures)At low temperatures volume of the container is larger. therefore intermolecular attractive forces are negligible and the volume of the particles also become negligible compared with the volume of the vessel.therefore the real gases act like ideal At Lower Temperatures.
Why Gay-Lussac laws are only applicable in gases?
Gay-Lussac's laws specifically deal with the relationship between pressure and temperature in a gas, and they are based on the assumption that gas particles are in constant motion and collide with each other and the walls of their container. This assumption is not valid for liquids or solids, where the particles are closely packed and do not move as freely as gas particles. Therefore, these laws are only applicable to gases.
What are high temperature plastics used for?
The high temperature plastics can only be used from the temperature of 135 degree Celsius and lower. Many others thought that high temperature plastics meant that it can handle extremely high temperature but they are wrong.
What is the properties of noble gases as a result of their stable electron configuration?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
