System International d'Unites (SI) -Answer The standard measurement system used in scientific literature & clinical laboratories. Henry's law -Answer The solubility of a gas in a liquid is directly proportional to the pressure of the gas about the liquid at equilibrium. Correlation between pressure, temperature, & solubility. -Answer As the pressure of a gas is doubled, its solubility is also doubled. The solubility decreases with an increase in temperature. Ultra-pure Rea...
