A law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.
‘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.’
‘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.’
‘Plot the Average Volume versus Temperature, print a hard copy of the graph, and describe how your results verify Charles's law.’
‘If the pressure is held constant, the ideal gas law yields Charles's law, V / T = constant (at constant P).’
Origin
Late 19th century: named after Jacques A. C. Charles (1746–1823), the French physicist who first formulated it.
