Oxygen and Nitrogen are the two gases that do not condense when air is cooled to 200 degrees Celsius. They remain as gases at this temperature.

Do gasses have volume?

No, nothing can have a negative volume. No such thing.


What is it that cools the air in a household refrigerator?

Modern electric fridges are cooled by the evaporation of a low boiling point liquid. The resulting gas is then compressed and cooled (in the fins at the back of the fridge) to condense it back to a liquid. It then goes through the cycle again and again. See link to animated drawing for details. The liquid/gas used in fridges manufactured before the mid 1980s was genereally a CFC (Chloroflourocarbon) but these were banned under the Montreal treaty in 1989 due to their damaging effect on the ozone layer. Currently they have been largely replaced by HCFC in modern fridges but HCFCs although not harmful to the ozone layer are powerful global warming gasses. Their use is due to be banned by 2030 if not sooner.D - Absorption of the heat from the air due to evaporation of the liquid refrigerant.


What happens to the volume of solids liquids and gasses as they warm and cool?

As solids are warmed, they expand and their volume increases. Conversely, as solids cool, they contract and their volume decreases. For liquids, warming causes expansion and an increase in volume, while cooling results in contraction and a decrease in volume. Gases behave differently as they expand when warmed and contract when cooled, with volume being directly proportional to temperature.


What gas is more ideal N2 or HBr and why?

Hydrogen and neon are similar in their behavior as nearly ideal gasses. Normally, deviations from ideal gas behavior become prominent as the temperature approaches the condensation (or equivalently boiling) point. Real gasses condense because of the attractive forces between the atoms and an ideal gas has no inter atomic forces. Neon condenses at 27 degrees Kelvin and hydrogen condenses at 20 degrees Kelvin. One expects neon to show more deviation from ideal gas behavior.


Does Neon have a mild or violent reaction?

Actually, Neon is one of the Noble Gasses, which are also known as the Inert Gasses, that make up the far right column of the periodic table. This family of gasses include Helium, Argon and even Radon. These gasses are called inert because they can't react with any other substance. This is because they already have eight valence electrons in their outer shell, rendering them unable to bond with any other atom. So, the answer is neither, Neon can't create a reaction at all.

What gasses condense?

Gases with low boiling points, such as water vapor, can condense into liquid form when cooled. Additionally, gases with high vapor pressure can also condense under the right conditions.


How is air seperated?

air is separated through the process of fractional distillation this is where the gasses are cooled until they become a liquid. then the liquids are heated the lighter gasses boil first and evaporate then condense back into a liquid.


What object can condense and form a star and possibly planets?

Solar Gasses. When a star explodes as a nova or a super-nova, it puts out large amounts of gasses that can re-condense to form planets and/or another sun(s).


Does gases contract when heated?

No, gasses expand when heated and contract when cooled.


What happens to a real gas as it cools from room temp to 0 dgrees kelvin?

As a real gas cools from room temperature to 0 degrees Kelvin, it undergoes a phase transition to a liquid state due to increased intermolecular forces. At absolute zero, the gas would become a solid, as molecular motion ceases.


Why is the air filtered before the gases are separated?

Because the gasses are compressed and cooled to -200 degress


Why do intake valves last longer than exhaust valves?

Intake valves are cooled by the gasses passing through them, exhaust valves are heated by the gasses passing through them and can be burned by overheating.


What are sodium cooled valves and how they work?

Sodium is a solid at room temperature and becomes a liquid at 97.5 degrees Celsius. Sodium cooled valves are exhaust valves in a cylinder head of an engine that open to release exhaust gasses that were formed due to combustion of fuel and air inside the cylinders and typically get very hot. The sodium cooled valves and exhaust valves filled with sodium inside, the sodium helps the valves be cooler than if they were just solid.


Why are gases not cooled before they enter a catalytic converter?

Catalytic Converters operate their best at high temperatures. Cooling the gasses would be counter productive.


How do you turn polluted water into a polluted gas?

To turn polluted water into polluted gas, one method is by heating the polluted water to its boiling point to convert it into vapor. The vapor can then be collected and cooled to condense it back into a liquid, which would contain pollutants in gas form. This process allows for the separation of pollutants from water.


Does Saturn have a presence of water?

saturn has water vapor in its atmosphere so i guess if the water would condense yes,but not drinkable to to the amonia methane and other non-breathable gasses in its atmosphere


What happens if steam is subjected to electric arc?

In the case of arc welding , moisture is superheated to steam , then further into Hydrogen and oxygen gasses, this usually produces a porous inferior weld, as the gasses are infused into the molten metal , and expand to form small voids , or pockets in the final cooled weld.
