ideal gas
« on: June 18, 2009, 03:17:35 PM »
ok, why is ideal gas valid at certain conditions?

lower pressure and higher temp ?

I'm thinking cause the molecules will be further apart under these conditions so they will behave as an ideal gas:


also, is there a formula to calculate the absolute temp

I have some mm values and temps ?


thanks again,

Ideal gas equation can be derived from the kinetoc theory of gases. What are assumptions in this theory?

It is valid at high temperature and very low pressure. becoz at these conditions the attractive forces among the molecules of a gas becomes less, so , no pressure or volume corrections are needed, which are to be utilized in case of real gas. So that's y ideal gases are valid for certain temperature..
