The Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.
The ozone depletion potential (ODP) of a chemical compound is the relative amount of degradation to the ozone layer it can cause, with trichlorofluoromethane (R-11 or CFC-11) being fixed at an ODP of 1.0.
In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how light propagates through that medium.
Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible.
The viscosity of a fluid is the measure of its resistance to gradual deformation by shear stress or tensile stress.
