Study Notes
Gas Movement and Properties
- Diffusion is the term used to describe the movement of gas molecules from an area of higher concentration to an area of lower concentration.
Gas Behavior
- At constant volume, the temperature and pressure of a gas are directly proportional, meaning that as temperature increases, pressure also increases, and vice versa.
Phase Change
- Condensation is the process by which a gas turns into a liquid.
Gas Volume
- At standard temperature and pressure (STP), one mole of a gas occupies a volume of 22.4 liters.
Gas Mixtures
- Dalton's Law of Partial Pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each gas.
