non ideal gases

What are some non ideal gases?

Re: non ideal gases

Increasing the amount of intermolecular forces causes more deviations from ideality, so gases that have a larger molar mass would be less ideal that gases with a lower molar mass. (E.g. CO2 would be less ideal than He)

Re: non ideal gases

all gases interact with each other in the real world making them non-ideal. But some are very close to a ideal which makes the ideal gas law a good approximation.

Re: non ideal gases

Most gases are non ideal. Any gas that has intermolecular forces and take up volume are non ideal.

Re: non ideal gases

Pretty much all gases are not ideal. an "ideal gas" is just a concept to help us be able to solve problems and equations assuming that the gas does not take up any volume or have any intermolecular forces (which non-ideal gases obviously do).

Re: non ideal gases

Almost all gases that you use in an experiment would be non-ideal, but it is easier to do calculations with ideal gases.

Re: non ideal gases

ideal gases are for the purpose of creating a problem, gases are usually non ideal

Any gas that exhibits intermolecular forces and takes up volume.

Re: non ideal gases

Most gases are non ideal. Ideal gases are used to make it easy to calculate properties of gases using the ideal gas law (PV = nRT) as long as the pressure isn't too high or the temperature isn't too low or else that will cause deviations in the calculations.
