1

the process of boiling is a form of evaporation

T

2

the boiling point of a liquid heated in an open container is determined by atmospheric pressure

T

3

the normal boiling point of a liquid is the temperature at which it boils when the liquid is at sea level

F

4

At a pressure of 760 mmHg, all liquids boil at the same temperature

F

5

a liquid can be made to boil at temperatures higher than its normal boiling point

T

6

A liquid can be made to boil at temperatures lower than its normal boiling point

T

7

In a liquid, vapor formation occurs within the body of the liquid

T

8

To compare the boiling points of 2 different liquids, the external pressure should be the same

T

9

If the external pressure (atmospheric pressure) increases, the boiling point decreases

F

10

Water would boil at a lower temperature in Utah compared to Mt. Everest

F

11

Water will boil if vapor pressure and atmospheric pressure are equal

T

12

Water will boil if vapor pressure = 735 torr and atmospheric pressure = 765 torr

F

13

Hydrogen bonds are extra strong London Forces

F

14

A London force is a very weak permanent dipole

F

15

The strength of the dipole-dipole interactions increase as the molecular polarity increases

T

16

All molecules with H atoms can participate in hydrogen bonding

F

17

In liquids, what is the relationship between boiling point and the strength of intermolecular forces

>boiling point = > intermolecular forces

18

In liquids, what is the relationship between vapor pressure magnitude and the strength of the intermolecular forces

> vapor pressure = < intermolecular forces
