A liquid will boil when...
Vapor pressure = equilibrium vapor pressure
atmospheric pressure = vapor pressure
The temperature reaches equilibrium
When the strength of the london dispersion forces = vapor pressure of the liquid
Liquid A is polar and can form hydrogen bonds with neighboring molecules. Liquid B is non-polar and has a similar mass as liquid A. Which of the following would be TRUE regarding these liquids?
Liquid A would have a higher heat of vaporization and a higher vapor pressure at a given temperature
Liquid A would have a higher heat of vaporization and a lower vapor pressure at a given temperature
Liquid A and liquid B would have similar heats of vaporization and vapor pressures.
Liquid A would have a lower heat of vaporization and a higher vapor pressure compared to liquid B

If the temperature of a gas in a sealed rigid container increases from 5 C to 15 C...the pressure will...
Increase by a factor of 3

Which of the following molecules would be polar?
CCl4
CO2
CS2
SO2
In comparing BeS and CS2 ....which of the following would have the lowest MP and why?
BeS because it has fewer electrons and weaker london dispersion forces compared to CS2
BeS because the charge densities are higher than in CS2
CS2 because it is molecular while BeS is ionic
CS2 because it non-polar and can only form LDF's while BeS is polar and can form DDF's and LDF's.
