exam 1

Question 1

longer, less compact molecules make

Answer 1

higher LDF

Question 2

higher the LDF

Answer 2

Higher the boiling point

Question 3

more electrons (larger molecules) and higher polarizability

Answer 3

Stronger LDF

Question 4

ionic bonds typically have

Answer 4

higher boiling points

Question 5

vaporization is higher with

Answer 5

increased temp (more kinetic energy), increased surface area and decreased IMF

Question 6

enthalpy of vaporization is higher if

Answer 6

IMFs are higher (takes more energy)

Question 7

volatile

Answer 7

liquids that evaporate easy

Question 8

The opposite process of vaporization is

Answer 8

condensation

Question 9

condensation is a

Answer 9

exothermic process that happens at a slower rate of vap

Question 10

dynamic equilibrium

Answer 10

rate of vap and condensation are equal so no gain/loss of liquid

Question 11

vapor pressure depends only on

Answer 11

liquids IMF and temp (not volume)

Question 12

high vapor pressure if

Answer 12

IMFs are weaker (liquid is more volatile)

Question 13

conditions of capillary action

Answer 13

cohesive forces are weaker than adhesive forces
