Vocabulary for IPC
| Question | Answer |
|---|---|
| pH | measure of of how acidic or basic something is; acid <7 neutral = 7 basic >7 |
| electrolyte | an atom with a charge; will conduct electricity |
| reactivity | tendency to react with other chemicals (lose electrons or gain electrons) |
| solar cells | absorb sunlight for solar energy |
| Newton's laws | explain 1. Inertia 2.Acceleration and 3. Action-Reaction |
| frequency | measure of the number of waves per second; measured in Hz (cycles per second) |
| oxidation | a chemical reaction where electrons are lost |
| momentum | based on mass and velocity |
| wave | includes a crest and a trough, has an amplitude, wavelength, and a frequency |
| heat transfer | movement of thermal energy (heat) from a source to another object; conduction, convection, & radiation |
| buoyancy | ability of a fluid to push up on a floating object; if the fluid has high density, it will have high buoyancy |
| solubility | ability to dissolve; solids affected by temperature,stirring and surface area; gases affected by temperature, stirring and air pressure |
| solute | gets dissolved ex: salt, sugar, carbon dioxide |
| solvent | does the dissolving ex: water, soda |
| viscosity | how slow does it flow ex: syrup or oil had greater viscosity than water |
| acceleration | change in speed; speed up or slow down |
| density | how many atoms per square inch; how crowded the atoms are g/mL or g/cm^3 |
| efficiency | how much work it takes to use a machine compared to how much work the machine saves |
| nuclear reactions | splitting apart of an atom (fission) or joining of two atomic nuclei (fusion) |
| endergonic | chemical reactions that need energy; feel cold because they absorb it |
| exergonic | chemical reactions that release energy; usually as light or heat |
| solution | mixture of solvent and solute |
| law of conservation of energy | you can't create or destroy energy, only transfer it: ex. lightbulb transfers electrical energy to light and heat; car transfers chemical energy (gas) into mechanical energy (movement) and heat |
| law of conservation of mass | you can't create or destroy atoms; is why we balance chemical equations; is why mass before the reaction = mass after the reaction |
| force | push or pull; measured in Newtons |
| physical properties | characteristics you can observe without changing the materials; ex: size, shape |
| work | force on an object over a distance; measured in joules |
| chemical properties | any characteristics, such as flammability, that indicate it can undergo a chemical change |
| power | amount of work done in a certain amount of time; measure in watts |
| circuit | pathway for electricity: series circuit- one pathway for electricity parallel circuit- two or more pathways for electricity |
| accuracy | how close the measurements are to the real answer |
| precision | how consistent the measurements are |
