In the 17th century, an Irish chemist named Robert Boyle began to do quantitative experiments on gases. Using a gigantic J-shaped tube that he had mounted on the side of his house, Boyle studied the relationship between the pressure of the trapped gas and its volume. After collecting all of his data, Boyle noticed that the product of the pressure and volume for the gas was constant. This is represented by the equation PV = k, where P is pressure, V is volume, and k is a constant number at a specific temperature for a given sample of air. Boyle's law can be used to predict the new volume of a gas when the pressure is changed (at constant temperature). Practice problem |
