Questions and Answers
What does Boyle's Law state about the relationship between pressure and volume at constant temperature?
Pressure is inversely proportional to volume.
If the pressure on a gas increases from 1.0 atm to 1.4 atm, what happens to the volume of the gas?
The volume decreases.
In the equation $P_1V_1 = P_2V_2$, what do the symbols $P_1$, $P_2$, $V_1$, and $V_2$ represent?
$P_1$ = Initial Pressure, $P_2$ = Final Pressure, $V_1$ = Initial Volume, $V_2$ = Final Volume

Study Notes
Boyle's Law Overview
- Formulated by Robert Boyle in 1662; relationships between pressure (P) and volume (V) of gases.
- States that pressure and volume are inversely related when temperature is constant.
- The equation representing Boyle's Law: ( P_1V_1 = P_2V_2 ).
Key Concepts
- When volume increases, pressure decreases, and vice versa.
- Pressure and volume have a constant product at a given temperature.
- Robert Boyle lived from 1627 to 1691, contributing significantly to the field of chemistry and physics.
Equation Components
- ( P_1 ): Initial Pressure
- ( V_1 ): Initial Volume
- ( P_2 ): Final Pressure
- ( V_2 ): Final Volume
Applications of Boyle's Law
- Practical implications in pressure and volume calculations for gases under varying conditions.
- Critical for understanding gas behaviors in closed systems, such as engines and balloons.
Sample Problems
- Car with a volume of 12,000 L experiences pressure change from 1.0 atm to 1.4 atm; volume can be calculated using Boyle’s law.
- In a 3 L gas container at 5 atm where volume decreases to 2 L; new pressure can be determined by rearranging the law.
- A gas's initial volume of 1.8 L at 17.5 psi reduces to 750 mL; conversion to atm required for pressure calculation.
