Can a gas that is under sufficient pressure to cause it to partially liquefy behave as an ideal gas ?

Question

jfraser · Answer

do you know the three main factors that an ideal gas $has \space to $ have?

anonymous · Answer

Ummm I think so .. do u mean the assumption?

jfraser · Answer

yes, the 3 assumptions about the behaviors of ideal gases

anonymous · Answer

- volume of molecules is negligible compared to the total volume 
- collisions are elastic 
- no intermolecular forces present

jfraser · Answer

so which of those may not be true if you've got so much gas present that it's forced to liquefy?

anonymous · Answer

Intermolecular forces are present

jfraser · Answer

so if one of the assumptions is not true, can the gas behave as an 'ideal' gas?

anonymous · Answer

No .. ok I knew tht ^^ but I hav another question 
Suggest a reason why propane is used instead of butane for gas stoves in cold climates in the winter ?
