bio2 water property
this is when the group did the water properties and these are the terms
| Term | Definition |
|---|---|
| Refraction | the bending or turning of light waves when it passes through water. |
| Reflection | projecting back an image through light without absorbing it. |
| Ion | an atom or group of atoms that has acquired an electric charge by gaining or losing one or more electrons. |
| Cation | an ion or group of ions that have a positive charge. |
| Anion | an ion or group of ions that have a negative charge. |
| Electrolyte | a chemical compound that breaks into seperate ions when it is dissolved or molten to produce an electrically conductive product. |
| Solvent/Universal Solvent | the liquid in which a solute is dissolved to form a solvent. |
| Solute | the component in a solution, dissolved in the solvent. |
| Polar/Polarity | a molecule with a net dipole as a result of the opposing charges. |
| Compound | a substance that is composed of two or more seperate elements. |
| Boiling Point | the point where water turns to vapor. |
| Freezing Point | the point at which a liquid turns to a solid. |
| Specific Heat | the heat required to raise the temperature of the unit mass of a given substance by a given amount. |
| Melting Point | the temperature at which a given solid will melt. |
| Salt Water | water containing a large amount of salt. |
| Pure Water | water that has no impurities. |
| Hot Water | water thats temperature is higher than 68-77 degrees Fahrenheit. |
| Cold Water | water thats temperature is less than 50 degrees Fahrenheit. |
| Temperature | a measure of the warmth or coldness of an object or substance with referance to some standard value. The temperature of two systems is the same when the systems are in thermal equilibrium. |
| Increments | the act or process of increasing growth. |
| Cohesion | the action or fact of forming a united whole. |
| Physical Property | any used to characterize matter and energy and their interaction. |
| Intermolecular Force | forces that act between stable molecules or between functional groups of macromolecules. |
| Molecules | a group of atoms bonded together, representing the smallest fundamental unit of a chmical compound that can take part in a chemical reaction. |
| Adhesion | the molecular force of attraction in the area of contact between unlike bodies that acts to hold them together. |
| Evaporation | the process by which a liquid changes into a gas. |
| Density | a property of matter representing the mass per unit of volume. |
| Fresh Water | water thst is not salty snd has little or no taste, color, or smell. Most lakes and rivers are made up of fresh water. |
| Condensation | water vapor becoming a liquid. |
| Precipitaion | any type of liquid or solid water that falls to Earth's surface, such as rain, snow, sleet, or hail. |
| Water Vapor | water in the form of gas. |
| Surface Tension | the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together. |
| Atom | the basic unit of a chemical element. |
| Fahrenheit | of or denoting a scale of temperature on which water freezes at 32° and boils at 212° under standard conditions. |
| Conductivity | the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity. |
| Controlled Variable | the terms "dependent variable" and "independent variable" are used in similar but subtly different ways in mathematics and statistics as part of the standard terminology in those subjects. |
| Dependent | contingent on or determined by. |
| Independent | not depending on another for livelihood or subsistence. |
