The gas molecules interact with one another
Wiki User
∙ 9y agoAn ideal gas has particles with zero volume that have no attractive or repulsive forces between them. Real gases have particles with a definite shape and volume. They also have weak attractive forces to each other. The larger the volume and the stronger the forces, the less ideal the gas will be.

What is the characteristic of 1 mole of gas at stp?
1 mole of an ideal gas at STP occupies 22.4 liters. If STP is 'close' to the boiling point a real gas may deviate from ideal behavior and thus the volume will not be as predicted.
What form of the ideal gas law would you use to calculate the volume of the gas?
Make V explicit in the general for of the gas law: P.V = n.R.T then you get V = (n.R.T) / P
Would a gas whose molecules were true geometric points obey the ideal gas law?
If gas molecules were true geometric points (ie had zero volume) AND had zero intermolecular interaction (such as attraction or repulsion), then the gas would obey the ideal gas law. Gases composed of small, non-interactive molecules (such as helium gas) obey the ideal gas law pretty well (as long as the gas is low density and temperature is rather high). For non-ideal gases, at least two correction factors are often used to modify the ideal gas law (correcting for non-zero volume of gas molecule and intermolecular attraction) such as in the Van der Waals equation for a real gas.
What form of the ideal gas law would you use to calculate the volume of a gas?
V=nRT/P
In an ideal gas compared to a real gas at very high pressure occupies?
A 'real' gas would occupy a higher volume as compared to the same amount of gas would have when 'idealistically' calculated by the 'ideal' gas law. The 'eigen' volume (its own molecular dimension) is to be taken in account at high pressure.
What characteristic makes a gas non-ideal?
The gas molecules interact with one another
What would make gas non ideal?
The gas molecules interact with one another
What is a characteristic of 1 mole of gas at STP?
The volume is 22,710 980(38) litres for the ideal gas.

What would make a real gas as close to ideal as possible?
High temperature; low pressure.
Can an ideal gas turn into a solid?
An ideal gas is an abstraction - a simplification. No real gas behaves exactly like an "ideal gas". The reason an ideal gas is used is because (a) the math is simpler, and (b) this is close enough for real gases, in many cases. Thought this is often not stated explicitly, we can safely assume that an "ideal gas" is supposed to remain a gas, regardless of the temperature and pressure.

What characteristics make a gas non-ideal?

What kind of mass does the ideal gas have?
An ideal gas is assumed to have "point mass" - i.e. each molecule of gas occupies no intrinsic volume, thus the ideal gas is infinitely compressible since the molecules will never overlap as they are compressed like they would in a real gas.
