3.2 Properties of Solids

What is vapor pressure?

• The pressure exerted by a liquid on its container.

• The pressure exerted by a vapor back down on the liquid from which it evaporated.

• The pressure exerted by a gas above a solid.

• The pressure required to boil a liquid.

How does an increase in temperature affect the vapor pressure of a liquid?

• It decreases the vapor pressure.

• It increases the vapor pressure.

• It has no effect on the vapor pressure.

• It first decreases then increases the vapor pressure.

Based on the provided graph, which liquid has the weakest intermolecular forces?

• Propanone

• Ethanol

• Water

• Ethanoic acid

What is a characteristic property of ionic solids?

• They are ductile and malleable.

• They conduct electricity in solid form.

• They are brittle and can be easily shattered.

• They have low melting points.

Which statement is true about molecular solids?

• They are composed of ionic compounds.

• They typically have high melting points.

• The forces holding their molecules together are relatively weak.

• They conduct electricity in solid form.

What is a defining characteristic of covalent network solids?

• They are composed of individual molecules.

• They have relatively low melting points.

• They form extremely strong structures due to repeating networks of covalent bonds.

• They are typically good conductors of electricity.

Which of the following is an example of a covalent network solid?

• Ice

• Naphthalene

• Diamond

• Sodium chloride
