Water
Term | Definition |
---|---|
freezing point | the temperature at which a liquid turns into a solid when cooled |
boiling point | the point at which water turns to vapor |
surface tension | the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together |
cohesion | the action or fact of forming a united whole |
adhesion | the action or process of adhering to a surface or object |
melting point | the temperature at which a given solid will melt |
specific heat | the amount of heat required to raise the temperature of 1 g. of a substance to 1° C |
intermolecular force | forces that act between stable molecules or between stable molecules or between functional groups of macromolecules |
molecule | a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction |
evaporation | the process by which a liquid changes into a gas |
universal solvent | due to its polarity and ability to dissolve many different solutes, water is this |
solute | the component in a solution that is dissolved dissolved in the solvent |
ion | an atom or molecule with a net electric charge due to the loss or gain of one or more electrons |
polarity | the state of having a molecule with a net dipole as a result of opposing charges |
hydrophobic | hates water |
hydrophilic | loves water |
Heat Vaporization | The amount of heat required to convert a liquid into a gas at constant temperature and pressure. |
capillary action | is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity. In biology, we refer to cohesion and adhesion forces acting together. |
