The total pressure exerted by the mixture of air and water vapour is equal to the sum of pressures which each constituent would exert, if it occupied the same space by itself. This statement is called

A. Kinetic theory of gases

B. Newton's law of gases

C. Dalton's law of partial pressures

D. Avogadro's hypothesis
