Question | Answer |
---|---|
pH | measure of hydrogen ions (H+) in a solution on a scale from 0-14 acid (H+)<7 neutral(7) Base (OH-)>7 |
electrolyte | a substance dissolves into ions and produces an electric current |
reactivity | tendency to gain or lose electrons |
solar cells | device that absorbs radiant energy from the sun. aka: photovoltaic cell |
Newton's laws | explain inertia, constant acceleration and momentum |
mechanical advantage | number of times a machine multiplies the effort force applied to it |
oxidation | reaction in which atoms in an element lose electrons |
momentum | property of a moving object based on its mass and velocity |
wave properties | rhythmic property that transfers energy ; transverse or compressional |
heat transfer | movement of thermal energy; conduction, convection, & radiation |
buoyancy | ability of a fluid to exert an upward force |
solubility | maximum amount of solute dissolved in a solvent at a given temperature |
solute | substance being dissolved ex: kool-aid, sugar |
solvent | substance doing the dissolving ex: water |
viscosity | a fluids resistance to flow ex: syrup or oil had greater viscosity than water |
acceleration | rate of change in velocity; speed up, slow down, or change direction |
density | mass per unit of volume; measurment can be g/mL or g/cm^3 |
efficiency | measure of work put in a machine compared to work done by a machine |
nuclear reactions | splitting apart of an atom (fission) or joining of two atomic nuclei (fusion) |
endergonic | chemical reactions that require energy |
exergonic | chemical reaction that release energy; usually light or heat |
solution | mixture that appears to have the same composition color, density, and taste throughout; made up of two parts; solute and solvent |
law of conservation of energy | energy is not created or destroyed; it changes forms; ex: electrical energy to heat energy (toaster) |
law of conservation of mass | mass is not gained or lost; it changes forms; ex: liquid to gas |
force | push or pull; measured in Newton's * formula f=ma |
physical properties | transfer of energy when force is applied to an object; measured in joules *formula w=fdcharacteristics you can observe without changing the materials; ex: size, shape |
chemical properties | any characteristics, such as flammability, that indicates it can undergo a chemical change |
power | amount of work done in a certain amount of time; measure in watts *formula P=w/t |
work | transfer of energy when force is applied to an object; measure in joules. *formula w=fd |
circuit | pathway for electricity: series circuit- one pathway for electricityparallel circuit- two or more pathways for electricity |
