Gaseous molecules refer to substances that exist in a gaseous state at a given temperature and pressure. These molecules have weak intermolecular forces and move freely within their container.
The mathematical relationship between pressure (P), volume (V), temperature (T), and number of moles (n) for an ideal gas.
States that at constant temperature, the volume of a given amount of gas is inversely proportional to its pressure.
Charles's Law: States that at constant pressure, the volume of a given amount of gas is directly proportional to its absolute temperature.
