The air we breathe is mostly a mixture of oxygen and nitrogen in the air is four times greater than the amount of oxygen which of these two elements is the lighter?
Nitrogen is lighter than oxygen. Nitrogen gas (N2) has a molar mass of 28.02 g/mol, while oxygen gas (O2) has a molar mass of 32.00 g/mol. Since nitrogen is lighter, it makes up a larger portion of the atmosphere.
How can you get nitrogen out of the air?
Nitrogen can be separated from air through a process called fractional distillation, which takes advantage of the different boiling points of nitrogen and oxygen. During this process, air is cooled and condensed into liquid form, then gradually heated to separate nitrogen from other components in the air.
Which of these is a lighter than air craft?
Without having the information about what the options are there really is not any way to know which is lighter than aircraft. The rest of the information needs to be provided for the correct answer to be given.
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
Water vapor molecules rise in the atmosphere, causing them to form clouds and ultimately precipitation. This is because lighter molecules have more kinetic energy and therefore move faster, allowing them to rise above the heavier nitrogen and oxygen molecules.
What is the percent if the air is nitrogen?
Our air is about 79% Nitrogen.
Heated air that is lighter than surrounding air will do what?
Heated air that is lighter than surrounding air will rise, as it is less dense. This process creates convection currents, with cooler air moving in to replace the rising warm air.
Why does heated air arise?
Cause its lighter than room temperature air..
Is nitrogen lighter than air?
If you are asking whether nitrogen is less dense than air and will float on top of it, then yes, nitrogen is "lighter," albeit only slightly. More accurately, nitrogen, which is a constituent gas of air, is less dense than air, not lighter. The density of air at standard temperature and pressure is 1.292 kg/m3. The density of nitrogen is 1.251 kg/m3.
What happens when water vapor is lighter than nitrogen or oxygen?
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
What happen to air when heated it will move up or down?
When air is heated, it becomes less dense and therefore lighter than the surrounding cooler air. This lighter, warm air will rise because of the buoyant force. Conversely, when air is cooled, it becomes denser and therefore heavier, causing it to sink.
What happens when heated air is lighter than the surrounding air?
When heated air is lighter than the surrounding air, it will rise due to convection currents. This process is known as thermal expansion, where hot air becomes less dense and more buoyant, causing it to ascend. This can lead to the formation of clouds and eventually precipitation.
Why is nitrogen heavier than air?
No. The atmosphere is roughly 80% N2, 20% O2, and about 1% of other trace gases. The molecular mass of N2 is about 28, the molecular mass of O2 is about 32. So, no O2 is not lighter than air, it is slightly heavier.
Why do helium and hot air balloon's rise?
Helium and hot air balloons rise because the air inside them is lighter than the surrounding air. Helium is lighter than the nitrogen and oxygen in the atmosphere, causing it to float upward. Similarly, hot air balloons rise because the heated air inside is less dense than the cooler air outside, creating lift.
What is the difference between a fresh air intake and regular intake on a vehicle?
The difference between a fresh air and a regular intake on a vehicle is the location of the inlet. Fresh air uses and inlet at the extreme front of the vehicle, while a regular intake can be anywhere and pull in heated air from the engine.

Is a hot air balloon filled with nitrogen?
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
What is the affect of increasing inlet air temperature in ci engine?
Increasing the temperature of the air at the inlet to any combustion engine will have a degrading effect on the engine's performance. Air expands when heated, and thus a lesser quantity of air is drawn into the combustion chamber. Indeed, turbochargers often have their air temperature cooled so as to allow more air in.
