I know that the more polar the bond between the H and A (if HA is an acid) is, the stronger the acid will be. what does it mean for a bond to be polar? is a bond more polar if it is more electronegative? how are bonds polar and how are bonds nonpolar? what is the difference ...

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?

**Chemistry**

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?

**Chemistry**

I don't 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?

Why do gases behave in a less ideal manner when in LOW TEMP. AND HIGH PRESSURE?
