### ideal gases

What are the qualifications of being an ideal gas?

### Re: ideal gases

An ideal gas is a theoretical gas that does not have any intermolecular attractive forces, does not take up space, and obeys the ideal gas law.

Adding on to that, most gases are not "perfectly" ideal but they're close enough to the ideal. Gases with large volumes, a high pressure, or a very low temperature can cause deviations from this ideal.

### Re: ideal gases

Ideal gases must follow the gas laws. They have no interaction and take up no volume.

### Re: ideal gases

To be an ideal gas, a gas must have no volume, have no intermolecular forces between each other, move randomly, and have perfectly elastic collisions with the walls of the container (no energy loss). I don't think ideal gases exist in reality, but they are a good model to use when calculating values using the ideal gas law (PV = nRT) as long as the pressure is not too high and the temperature is not too low.

### Re: ideal gases

Ideal gas molecules do not attract or repel each other.

Ideal gas molecules themselves take up no volume.

Ideal gases are elastic, have no intermolecular forces,

### Re: ideal gases

Ideal Gases have no mass and do not have any attractive force between them unlike a real gas which has attractions between molecules.

How do you distinguish if something is an ideal gas?

### Re: ideal gases

Something is an ideal gas if it does not take up volume and has no intermolecular attractive forces.

### Re: ideal gases

ideal gases obey gas laws, molecules take up no space and have no interactions!

### Re: ideal gases

How can you tell if something is an ideal gas? Will we be told?

### Re: ideal gases

Ideal gases do not take up space/volume, and don't have any interaction (no intermolecular forces of attraction). They have to satisfy/follow the (ideal) gas laws essentially.

### Re: ideal gases

Ideal gases have: elastic collisions between molecules, have no definite volume, and have molecules that are completely independent from one another.
On the other hand, real gases have: non-elastic collisions between molecules, have a definite volume, and have molecules that exert force on one another
