Refrigeration and Air Conditioning 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 Kinetic theory of gases Avogadro's hypothesis Newton's law of gases Dalton's law of partial pressures Kinetic theory of gases Avogadro's hypothesis Newton's law of gases Dalton's law of partial pressures ANSWER DOWNLOAD EXAMIANS APP
