L8 vap pressure

water have 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 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
• easily evaporate
• cannot diffuse
• freeze easily

When you increase your altitude, the air pressure 

• increases
• decreases
• stays the same

Evaporation occurs when water changes into 

• transpiration
• snow
• solid
• vapor

If the rate of boiling equals the rate of condensation...

• there is more liquid
• there is more vapor
• the system is in equilibrium
•  the system is working towards equilibrium

A water in a sealed container is cooled from 20⁰C to 10⁰C, its vapor pressure

• Decreases

• Increases

• Remains the same

When the vapor pressure of a liquid is equal to the atmospheric pressure, the liquid will

• Freeze

• Boil

• Melt

• Condense
