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