Flashcards
Boyle's Law
Boyle's Law
Boyle's Law describes the inverse relationship between volume and pressure of a gas at constant temperature and mass.
Boiling Point Factors
Boiling Point Factors
The atmospheric pressure affects the temperature at which water boils; higher pressure raises the boiling point.

Study Notes
- Boyle's Law explains the relationship between volume and pressure for a fixed amount of gas.
- The atmospheric pressure affects the temperature at which water boils.
- The evaporated particles have more speed and higher energy than the particles that remain.
- When a liquid becomes a gas, the particles break away from one another.
- According to Charles's Law, heating a balloon causes it to expand.
- Opening a bottle of air freshener allows people to smell it due to the process of evaporation.
