<P> In chemistry , Henry 's law is a gas law that states that the amount of dissolved gas is proportional to its partial pressure in the gas phase . The proportionality factor is called the Henry 's law constant . It was formulated by the English chemist William Henry , who studied the topic in the early 19th century . In his publication about the quantity of gases absorbed by water , he described the results of his experiments : </P>
