Question 1

Vapour Pressure

Answer 1

The pressure exerted by a vapour back down on the liquid which evaporated it

Question 2

What does increased temperature lead to?

Answer 2

Increased vapour pressure

Question 3

Do liquids w/ weaker intermolecular forces have high or low vapour pressure?

Answer 3

Higher vapour pressure

Question 4

Answer 4

Low boiling points

Question 5

Ionic Solids

Answer 5

Composed of ionic compounds in a crystal lattice

Question 6

Molecular Solids

Answer 6

Solids composed of covalently bonded compounds

Question 7

Properties of Ionic Solids

Ice, Naphthalene (moth balls), many polymers, and CO2

Question 10

Covalent Network Solids

Answer 10

Covalent compounds that have a repeating network of covalent bonds that creates a VERY strong structure

Question 11

Properties of Covalent Network Solids

Answer 11

Extremely high melting and boiling points, often oriented in multiple different directions
