The Gas Laws I. Gas laws - simple mathematical relationships between the volume, temperature, pressure, and amount of a gas II. Boyle’s Law: Pressure-Volume Relationship A. Robert Boyle discovered doubling the pressure reduces volume by ½ B. Kinetic-molecular theory explanation: 1. Pressure of gas caused by particles hitting container walls 2. If volume is decreased, then the number of collisions will increase, increasing pressure C. Boyle’s Law - the volume of a fixed mass of gas varies inversely with the pressure at a constant temperature 1. Mathematically: PV = k, where k is a specific constant for each gas 2. Also: P 1 V 1 = P 2 V 2 2. If a gas is cooled by 273 degrees below 0, then the volume decreases by

Charles’s law- the volume of a fixed mass of gas at constant temperature varies directly with the Kelvin temperature 1. V = kT, where k is a constant depending on quantity and pressure of gas 2. V 1 /T 1 = V 2 /T 2 Gay-Lussac’s Law: Pressure- Temperature Relationship A. Gay-Lussac’s Law- the pressure of a fixed mass of gas at a constant volume varies directly with the Kelvin temperature 1. Higher temperature particles move faster more collisions of particles higher pressure...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
