A common misconception about vapor pressure lowering is that the solute occupies some of the surface sites in the solution, reducing the percentage of solvent molecules that can
potentially overcome the attractive intermolecular forces and transition into the gas phase. (a)
Draw a particulate-level sketch of a nonvolatile molecular solute in water and use it to explain
why the misconception is incorrect. (b) What is the correct explanation for vapor pressure
lowering?

Why does the sun appear to be the brightest star in the sky? a- its apparent brightness is much greater than other stars. b- it burns more gas, making it brighter than any other star. c- it is the largest star in the galaxy, so it is the brightest star. d- its relative distance to earth is closer than the other stars.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
