Dont real gas molecules occupy volume, and have attractive forces? Do real gases become liquids? Why? Ideal gases cant do this.
I dont know what you just said, but i know that when an ideal gas is at a lower pressure, the molecules do not collide with the container as frequently, and that at a high temperature the molecules do collide frequently. What does this mean, does it even help me?
No. Reread what I asked. I gave you the answer. If you have no idea what I am writing of, you quickly need to reread your text on the failure of the assumptions of the ideal gas vs real gases.
Ok, i understand that for real gases you have to account for volume of particles, and that they have attractive forces that lower the pressure, that make the ideal gas law invalid, but what does that have to do with low temp and high pressure?
Is it because at high pressure, molecules have volume, and at low temperature gases move slowly and act like a liqud so they have attractive forces that decrease pressure?
