FLASHCARD QUESTION

Front

What is vapor pressure?

Back

Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature.

2.

FLASHCARD QUESTION

Front

How does temperature affect vapor pressure?

Back

As temperature increases, vapor pressure increases because more molecules have enough energy to escape the liquid phase.

3.

FLASHCARD QUESTION

Front

What is the relationship between boiling point and vapor pressure?

Back

A liquid boils when its vapor pressure equals the external pressure. Higher vapor pressure at a given temperature means a lower boiling point.

4.

FLASHCARD QUESTION

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions). They determine the physical properties of substances.

5.

FLASHCARD QUESTION

Front

Which type of intermolecular force is the weakest?

Back

London dispersion forces are the weakest type of intermolecular force.

6.

FLASHCARD QUESTION

Front

What is the normal boiling point of a substance?

Back

The normal boiling point is the temperature at which a liquid's vapor pressure equals 1 atmosphere (101.3 kPa).

7.

FLASHCARD QUESTION

Front

How does pressure affect the boiling point of a liquid?

Back

As external pressure decreases, the boiling point of a liquid decreases.
