Key Takeaways: Boyle's Law Chemistry Problems Simply put, Boyle's states that for a gas at constant temperature, pressure multiplied by volume is a constant value. This law is applicable to the ideal gases only where only pressure and volume subject to change. Example: A gas at 110kPa at 30.0°C fills a flexible container with an initial volume of 2.00L. P 1 V 1 = P 2 V 2 ∴ V 2 = P 1 V 1 /P 2 ∴ V 2 = 101.325 kPa × 0.6 dm 3 / 142.860 kPa ∴ V 2 = 0.426 dm 3. For example, the compression and expansion of gas lead to the need to equalize your ears, adjust your BCD, and make safety stops. This equation is used to solve Boyle's Law problems. Example: Gas having 150 cm 3 volume has pressure 120 cmHg. What will be the volume of this gas if the pressure becomes 3.00 atm? History and Derivation of Boyle’s Law. Boyle’s law, a relation concerning the compression and expansion of a gas at constant temperature. Chemistry: Boyle's Law (Gas Laws) with 2 examplesFor a gas, pressure and volume are inversely proportional. What is its volume at standard pressure? The Combined Gas Law combines Charles' Law, Boyle’s Law and Gay Lussac’s Law. Problem #4: A gas occupies 1.56 L at 1.00 atm. Figure \(\PageIndex{2}\): The pressure of a gas decreases as the volume increases, making Boyle's law an inverse relationship. Anglo-Irish chemist Robert Boyle (1627–1691) discovered the law and for it he is considered the first modern chemist. A few very interesting examples regarding Boyle’s Law in everyday life are discussed below: 1. Small boats fall into the "holes" and are engulfed by the sea. A few very interesting examples regarding Boyle’s Law in everyday life are discussed below: 1. Soda Cans/Bottles : You may have noticed that whenever a person opens a can or bottle of soda, the cap or the lid is opened slowly, allowing the gas inside to escape at a controlled rate.
