This particular gas law ia called Boyle's law, after the English scientist Robert Boyle, who first announced it in 1662. The law is described by the mathematical equation PV = K. It has become a basic law in chemistry. The trapped air acted much like a spring, exerting a force opposing its compression. Comment: Boyle's Law assumes that the temperature and amount of gas are constant. This law states that the product of the volume and pressure of a gas is constant at a constant temperature and mass. Anglo-Irish chemist Robert Boyle (1627–1691) discovered the law and for it he is considered the first modern chemist. The formula for boyle’s law is as follows: p₁ * V₁ = p₂ * V₂ . A gas law is a simple mathematical formula that allows you to model, or predict, the behavior of a gas. Boyle's Law Equation . There are a couple of ways of expressing the law as an equation. PV = k Where p1 and p2 are initial and final pressures; V1 and V2 are initial and final volumes; The reaction is iso-thermal; This formula is derived from the ideal gas law equation of pV = nRT. 2) Now, we can solve the problem using Boyle's Law: P 1 V 1 = P 2 V 2 (101.3) (2.0) = (88.144) (x) x = 2.27 L The balloon will not burst. Boyle's law is an ideal gas law where at a constant temperature, the volume of an ideal gas is inversely proportional to its absolute pressure. It was put forward by a physicist Robert Boyle in the 17th century, and has proved very beneficial for scientists involved in the study of properties of gases. An animation of Boyle’s Law, showing the relationship between volume and pressure when mass and temperature are held constant. This equation is an example of a gas law. The formula at the top of the page is Boyle's Law, named after the British chemist Robert Boyle (1627 - 1691). The law itself can be stated as follows: For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. Boyle’s Law Formula. Boyle’s Law Explained. It states that the volume of a fixed mass of gas at a constant temperature is inversely proportional to the pressure of the gas. Boyle’s Law Formula When the temperature of a gas is held constant, the pressure of the gas will be inversely proportional to the volume of the sample gas. Boyle called this effect “the spring of the air” and published his results in a pamphlet with that title. What Is Boyle's Law and Equation? The most basic one states: Boyle's gas law states that the volume of a gas is inversely proportional to the pressure of the gas when the temperature is held constant. Since we never knew the starting temperature, we … Put simply, when volume rises, pressure drops, and vice versa. The importance of Boyle’s law lies in being the first law to describe the behavior of gases. The mathematic equation is equally as simple. Boyle’s Law. Boyle's Law provides an important formula to calculate the effect of changing pressure on the volume of a gas, and vice versa. This phenomenon was discovered by Anglo-Irish Chemist, Inventor, and Physicist Robert Boyle; that is why known as Boyle’s Law. In 1662, Robert Boyle discovered the volume and pressure of gasses are inversely proportionate when held at a constant temperature. Boyle's Law relates the pressure and the volume of a gas. Figure \(\PageIndex{1}\) shows two representations of how Boyle’s law works. This implies that these two properties are inversely proportional.
