At SATP or STP, Generally yes. Dry air contains roughly (by volume):
* 78.08% nitrogen * 20.95% oxygen * 0.93% argon * 0.038% carbon dioxide All the above are relatively small, light, non-polar molecules, characteristics mimicking an ideal gas.
At normal ambient conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Generally, deviation from an ideal gas tends to decrease with higher temperature and lower density, as the work performed by intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
The ideal gas model tends to fail at lower temperatures or higher pressures, when intermolecular forces and molecular size become important. At some point of low temperature and high pressure, real gases undergo a phase transition, such as to a liquid or a solid. The model of an ideal gas, however, does not describe or allow phase transitions. These must be modeled by more complex equations of state.

When is helium an ideal gas?
when you blow the helieam air into the object. anwsered by : Megan Barrera who is in 4th
Is krypton an ideal gas?
No. Krypton gas is an element and therefore a pure substance.
What is retained by gas particles involved in elastic collisions?
Ideal Gas.
For ideal gas force of attraction between molecules?
In an ideal gas there is no attarcation between molecules. There is no such thing as an ideal gas it is a model that approximates the behaviour of real gases.
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.
How do you calculate temperature rise of compressed air?
by using ideal gas law
Ideal gas law to explain why a hot air balloon floats?
We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
What are examples of ideal gases?
An ideal gas is a gas that follows all the gas laws perfectly. An ideal gas is only a theoretical concept though. In order to have an ideal gas, the gas molecule must have no mass and absolutely no interaction with any other molecule. Several gases come close to this ideal (such as Helium), but none of them can fully achieve it.
Does air act like a fluid?
Gas is classified as a fluid because of the way it flows. Air is composed of gas.
Is hydrogen a ideal gas?
No, no real gas is actually an ideal gas.
In what condition does a particle act most like a ideal gas?
high temperatures, and low pressure. This increases the amount of entropy in the system. An ideal gas is created when entropy is at maximum value, which has never been reached.
What is meant by the term 'ideal gas'?
An ideal gas is a theoretical gas composed of a set of randomly-moving, non-interacting point particles. The ideal gas concept is useful because it obeys the ideal gas law. At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Many gases such as air, nitrogen, oxygen, hydrogen, noble gases, and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances.
Why cant a gas be an ideal gas?
There are ideal gases..

Is argon gas an ideal gas?
Strictly speaking no, as an ideal gas is simply a theoretical device. Though it can be treated as an ideal gas to an extent.
What is the R in the ideal gas law?
the ideal gas constant D:
What is an imaginary gas that conforms perfectly to the kinetic molecular theory callled?
That's called an "ideal gas". The behavior of real gases is quite similar to an ideal gas, except when the pressure is too high, or the temperature too low.That's called an "ideal gas".
