We've learned that there is a lot of space between gas particles, and they have the freedom to move about and fill up a container. Which type of gas will spread out the fastest at the same temperature and pressure? Cl2
O2
Ar
Ne
As the intermolecular forces in a substance strengthen, how is the vapor pressure affected?
A. The vapor pressure decrease at first, and then it will increase as the intermolcular forces strengthen.
B. The vapor pressure will increase because the molecules of the liquid phase are held together more tightly.
C. The vapor pressure will not be affected because there are no intermolecular attractions among gas particles.
D. The vapor pressure will decrease because the molecules of the liquid phase are held together more tightly.
