A law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.
‘If the pressure is held constant, the ideal gas law yields Charles's law, V / T = constant (at constant P).’
‘The properties of a gas are described by a series of equations known as the gas laws, these are Boyle's law, Charles's law, and the constant volume law.’
‘Plot the Average Volume versus Temperature, print a hard copy of the graph, and describe how your results verify Charles's law.’
‘Used in the context of a Charles's law analysis, I found the term confusing, as it seems to imply that different components of a gaseous mixture can occupy different volumes within the same container.’
Origin
Late 19th century: named after Jacques A. C. Charles (1746–1823), the French physicist who first formulated it.
