Water
Question | Answer |
---|---|
polar molecule | a molecule that has electrically charged areas |
surface tension | the tightness across the surface of water caused by the polar water molecules pulling on each other |
capillary action | the combined force of attraction among water molecules and with the molecules of surrounding materials |
solution | a mixture in which one substance is dissolved in another |
solvent | the part of a solution that is present in the largest amount and dissolves a solute; it DOES the dissolving |
evaporation | the process by which molecules at the surface of the liquid such as water absorbs enough energey to turn into a gaseous state such as water vapor |
condensation | the process by which a gas such as water vapor changes into a liquid such as water |
transpiration | the process by which plants release water vapor through their leaves |
specific heat | the amount of thermal energy required to raise the temperature of one kilogram of a substance by 1 degrees Celceus |
suspension | a mixture by which particles can be seen and easily seperated by settling or filteration |
solute | the part of a solution present in a lesser amount and dissolved by the solvent; this GETS DISSOLVED by another substance |
freezing point | the temperature at which a substance turns from a liquid to a solid |
boiling point | the temperature at which a liquid turns into gas |
cohesion | when water molecules attract to each other because of unlike charges (negative to positive) |
adhesion | the process of water molecules sticking to other substances |
density | the amount of mass in a given space |
pores | tiny openings in and between particles of rock and soil that may contain air or water |
