| Question | Answer |
|---|---|
| measure of hydrogen ions (H+) in a solution on a scale from 0 to 14 | pH |
| a substance dissolves into ions and produces an electric current | electrolyte |
| tendency to gain or lose electrons | reactivity |
| device that absorbs radiant energy from the sun (ie: photovoltaic cells) | solar cells |
| objects at rest remains at rest; objects in motion remain in motion | Newton's First Law |
| Force = mass x acceleration (F=ma) | Newton's Second Law |
| For every action there is an equal and opposite reaction | Newton's Third Law |
| number of times a machine multiplies the effort force applied to it | mechanical advantage |
| reaction in which atoms in an element lose electrons | oxidation |
| property of a moving object based on its mass and velocity | momentum |
| rhythmic property that transfers energy (examples: transverse and longitudinal) | wave properties |
| movement of thermal energy; conduction, convection, and radiation | heat transfer |
| ability of a fluid to exert an upward force | buoyancy |
| maximum amount of solute dissoved in a solvent at a given temperature | solubility |
| temperature, particle size, pressure, and concentration | 4 factors that affect solubility |
| substance being dissolved (ex: kool-aid, sugar) | solute |
| substance doing the dissolving (ex: water) | solvent |
| a fluid's resistance to flow | viscosity |
| rate of change of velocity; speed up, slow down, or change direction | acceleration |
| mass per unit of volume; measurement can be in g/mL or g/cm3 | density |
| measure of work put in a machine compared to work done by a machine | efficiency |
| splitting apart of an atom (fission) or joining of two atomic nuclei (fusion) | nuclear reactions |
| chemical reactions that require energy | endergonic |
| chemical reactions that release energy; usually light or heat | exergonic |
| mixture that appears to have the same composition, color, density, and taste throughout; made up of 2 parts; solute and solvent | solution |
| energy is not created or destroyed; it changes forms (ex: electrical energy to heat energy (toaster)) | laow of conservation of energy |
| mass is not created or destroyed; it changes forms (ex: liquid to gas) | law of conservation of mass |
| one pathway for electricity | series circuit |
| two or more pathways for electricity | parallel circuit |
| push or pull; measured in Newton's (F=ma) | force |
| transfer of energy when force is applied to an object; measure in joules (W=fd | work |
| characteristics you can observe without changing the materials; ex: size, shape | physical properties |
| any characteristic, such as flammability, that indicates it can undergo a chemical change | chemical properties |
| amount of work done in a certain amount of time; measure in watts (P=w/t) | power |
