Question 5

The rate of condensation depends on what?

Answer 5

o The rate of condensation depends on the temperature the IMF, and the concentration in the gas phase

Question 6

Answer 6

the partial pressure of a substance in equilibrium with its condensed phase (liquid or solid). The pressure of the vapor over a liquid or solid at equilibrium

Question 7

The rate of evaporation depends on what?

Answer 7

o The rate of evaporation depends on the temperature and the IMF

Question 8

The vapor pressure depends on what?

Answer 8

o The vapor pressure for any pure liquid then depends only on the temperature and the IMF

Question 9

What is the relationship between vapor pressure and IMFs?

Answer 9

 Vapor pressure and IMF have an inverse relationship

Question 10

Define boiling point in terms of vapor pressure

Answer 10

o The boiling point is the temperature at which the vapor pressure equals the total pressure
