Henry's Law for Gas Solubility
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Henry's law states a gas's solubility in a liquid is directly proportional to that gas's partial pressure above the liquid, at fixed temperature.
Show
A diver's blood dissolves far more nitrogen at depth's high pressure than at the surface, so ascending too fast lets that nitrogen bubble out.
Watch for
Henry's law covers solubility as pressure changes at fixed temperature, not a simultaneous temperature change.
