Real vs. Ideal

I think I read yesterday that no gas behaves 100% ideally but under certain conditions (such as low pressure and high temperatures) gases behave nearly ideally. Then you can use the ideal gas law...

 

Well, it is chemistry so as you expect, nothing is ideal. You can never find exact info using PV=nRT.
So always just assume it is ideal and use that equation.
But you should that why nothing is an ideal gas.

 

ideal gas is basically a hypothetical situation. we just assume that 1) there are no intermolecular forces between the gas molecules and 2) occupy a negligable volume compared to the container. this is done so that PV=nRT can be used to calculate stuff.

real gases are exactly that... real lol. that formula is not valid anymore, but if we just tweek it a bit to take into considerations those two assumptions, we are good to go.

Hope that helped!

 

i'll tell you where. a couple points less on the DAT. haha =)
