Study Notes
Gas Laws
- Boyle's Law states that for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure.
- According to Charles's Law, if the pressure is kept constant, the volume of a fixed mass of gas will change in direct proportion to the temperature on the Kelvin scale.
- Gay-Lussac's Law states that the pressure of a gas is directly proportional to its Kelvin temperature if the volume is kept constant.
Ideal Gas Law
- The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature in Kelvin.
Dalton's Law of Partial Pressures
- According to Dalton's Law, the total pressure exerted by a mixture of gases at constant volume and temperature is the sum of the partial pressures of each gas.
