Vapour Pressure Check-In

Water has a low vapor pressure because

• it has strong london dispersion forces acting between its molecules

• it has strong hydrogen bonds acting between its molecules

• it has a weaker force of attraction between its molecules

• it is very volatile

The lower the boiling point, the ___ the intermolecular forces.

• stronger
• weaker

The strength of intermolecular forces varies between liquids; therefore, they will have

• different equilibrium vapor pressure

• the same equilibrium vapor pressure

• different temperatures

• the same amount of kinetic energy

Liquids with weak intermolecular forces

• contain a lot of kinetic energy

• are more volatile

• cannot diffuse

• freeze easily

Why does a gas with a lower vapor pressure have a higher boiling point?

• its molecules need more energy in order to break free from strong attraction

• there are strong forces of attraction between its particles

• it has a lower volatility

• all of the above
