Final answer:
Boyle's law, represented by the equation P1V1 = P2V2, describes the relationship between the pressure and volume of a gas at constant temperature. It allows for predicting gas behavior based on changes in volume and pressure.
Step-by-step explanation:
Boyle's law, represented by the equation P1V1 = P2V2, is a gas law that describes the relationship between the pressure and volume of a gas at constant temperature. It states that the product of the initial pressure and volume is equal to the product of the final pressure and volume. Boyle's law can be used to compare changing conditions for a gas and predict its behavior.
For example, if two containers with different volumes are connected and the volume of one container is changed, the gases will move from higher pressure (lower volume) to lower pressure (higher volume), following Boyle's law.
This gas law was first announced by the English scientist Robert Boyle in 1662 and it allows for the mathematical modeling of gas behavior.
