Charles's law relates gas volume to temperature at constant pressure. Formula: V1/T1=V2/T2, where V1 and T1 are initial values. Temperature increase causes volume increase, decrease causes volume decrease
Gas is a collection of molecules in continuous random motion with increasing speeds. Ideal gas model simplifies gas behavior but doesn't apply to real gases. Gas laws describe relationships between variables when others are constant
Boyle's law describes the inverse relationship between gas pressure and volume. Robert Boyle published the law in 1662, confirming Towneley and Power's discovery. Edme Mariotte independently discovered the same law in 1679
Avogadro's law states that equal volumes of gases contain the same number of molecules. The law relates gas volume to the amount of substance present at constant temperature and pressure. The law is a specific case of the ideal gas law
Charles's law describes gas expansion when heated. Volume increases directly with Kelvin temperature at constant pressure. Equation: V = kT, where k is constant for specific pressure and amount
Torricelli's 1643 experiment demonstrated mercury support in inverted tube. Boyle independently studied air elasticity in 1662. Mariotte independently found air volume-temperature dependency in 1676
