Chempal-TAKS IPC Voc

Anderson-- Arp HS --Vocabulary for TAKS IPC

QuestionAnswer
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
