What is a physical property?

• A characteristic that can only be observed with a chemical reaction

• A characteristic that can be observed or measured without changing the substance

• A description of how a substance changes in the presence of another substance

• A measurement that can only be taken when a substance is in a gaseous state

What is the boiling point of a substance?

• The temperature at which a liquid freezes

• The temperature at which a gas condenses into a liquid

• The temperature at which a liquid turns into a gas

• The temperature at which a solid turns into a liquid

Which of the following statements is true about alcohols?

• Alcohols have high boiling points and do not evaporate easily

• Alcohols cannot evaporate

• Alcohols have low boiling points and evaporate easily

• Alcohols have high boiling points and evaporate easily

What is the relationship between the size of alcohols and their boiling points?

• As size increases, boiling points decrease.

• As size increases, boiling points increase.

• Size has no effect on boiling points.

• As size decreases, boiling points increase.

Why do larger alcohols require more energy for their boiling points?

• Due to the decreasing strength of the intermolecular forces.

• Because they are less volatile.

• Due to the increasing strength of the intermolecular forces.

• Because they have lower molecular weights.

What is the definition of miscibility?

• The ability of one solid to mix with another solid

• The ability of one liquid to mix with (dissolve in) another liquid

• The ability of one gas to mix with another gas

• The ability of one liquid to separate from another liquid
