Boiling Point
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. - WikipediaEXIT.
Melting Point
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa. - WikipediaEXIT.
Water Solubility
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq). - WikipediaEXIT.
Henry’s Law
In physical chemistry, Henry’s law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry’s law constant. It was formulated by the English chemist William Henry, who studied the topic in the early 19th century. - WikipediaEXIT.
Viscosity
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of “thickness”: for example, syrup has a higher viscosity than water, and syrup is thicker than water. - WikipediaEXIT.
Polarizability
Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. It is a property of all matter, inasmuch as matter is made up of elementary particles which have an electric charge, namely protons and electrons. When subject to an electric field, the negatively charged electrons and positively charged atomic nuclei are subject to opposite forces and undergo charge separation. - WikipediaEXIT.
Density
The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. - WikipediaEXIT.
Flash Point
In chemistry, the flash point of a volatile material is the lowest temperature at which its vapors ignite if given an ignition source. The flash point is sometimes confused with the autoignition temperature, the temperature that causes spontaneous ignition. - WikipediaEXIT.
Molar Volume
In chemistry and related fields, the molar volume of a substance is the occupied volume divided by the amount of substance at a given temperature and pressure. It is equal to the molar mass divided by the mass density. - WikipediaEXIT.
Log-KoA: Octanol-Air
Coefficient of the partitioning of the chemical between octanol (an organic solvent) and air.
Log-KoW: Octanol-Water
Coefficient of the partitioning of the chemical between octanol (an organic solvent) and water.
Molar Refractivity
Molar refractivity, is a measure of the total polarizability of a mole of a substance and is dependent on the temperature, the index of refraction, and the pressure. - WikipediaEXIT.
pKa Acidic Apparent
This value could be acidic or basic. Not every chemical has an acidic or basic center, so for some substances, there might not be a value.
Vapor Pressure
Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. - WikipediaEXIT.
Surface Tension
Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged. - WikipediaEXIT.
Index of Refraction
In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. - WikipediaEXIT.
Thermal Conductivity
The thermal conductivity of a material is a measure of its ability to conduct heat. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. - WikipediaEXIT.
