Laplace's law:
A principle of physics which states that the tension on the wall of a sphere is the product of the pressure and the radius of the chamber. Also that the tension is inversely proportional to the thickness of the wall. This is Laplace's law.
Henry's law:
Henry's law is a gas law that states that the amount of dissolved gas in a liquid is directly proportional to its partial pressure above the liquid.
Raoult's law:
It states that for any solution, the partial pressure of each volatile component in the solution is directly proportional to its mole fraction
