Boyle’s Law
Boyle’s Law describes the inverse relationship between the pressure and volume of a gas at constant temperature. As the pressure on a gas increases, its volume decreases proportionally, and vice versa.
This relationship can be expressed mathematically as:
P₁V₁ = P₂V₂

After you’ve mastered these topics, come back to the Boyle’s and Charles Law Gizmo to see how you can apply them to real-world situations.
where:
- P₁ and P₂ are the initial and final pressures of the gas, respectively
- V₁ and V₂ are the initial and final volumes of the gas, respectively
Applications of Boyle’s Law
Boyle’s Law has numerous applications in real-world situations, including:
- Scuba diving:As scuba divers descend deeper into the ocean, the pressure on their bodies increases. Boyle’s Law explains why their lungs shrink in volume at greater depths.
- Pressure cookers:Pressure cookers use Boyle’s Law to create a high-pressure environment inside the cooker. This increased pressure raises the boiling point of water, allowing food to cook faster.
- Air compressors:Air compressors use Boyle’s Law to increase the pressure of air by reducing its volume. This compressed air is then used for various applications, such as powering pneumatic tools.
Limitations of Boyle’s Law
Boyle’s Law assumes that the temperature of the gas remains constant. However, in real-world situations, temperature changes can occur, affecting the accuracy of Boyle’s Law calculations.
Additionally, Boyle’s Law does not apply to gases at very high pressures or very low temperatures, where the behavior of gas molecules deviates from ideal gas behavior.
Charles’ Law
Charles’ Law describes the relationship between temperature and volume in a gas. It states that the volume of a gas is directly proportional to its absolute temperature, assuming constant pressure. In other words, as the temperature of a gas increases, its volume also increases, and vice versa.
Applications of Charles’ Law
- Hot air balloons: As the air inside a hot air balloon is heated, it expands and becomes less dense than the surrounding air, causing the balloon to rise.
- Gas cylinders: Charles’ Law is used to calculate the volume of gas that can be stored in a cylinder at a given temperature.
- Thermometers: Some thermometers use the expansion of a gas (such as mercury or alcohol) to measure temperature.
Limitations of Charles’ Law, Boyle’s and charles law gizmo
- Charles’ Law is only accurate for ideal gases, which do not exist in reality.
- The law does not apply at very high pressures or low temperatures, where the behavior of gases deviates from ideal behavior.
