|
||||
|---|---|---|---|---|---|
| Pure Substance | any element or compound, a substance is the same throughout and has a fixed chemical composition
🗑
|
||||
| Mixture | two or more substances mixed together without being chemically combined. The substances can be separated without a chemical reaction.
🗑
|
||||
| Physical Properties | a substance's color, odor, density, melting point and boiling point, ductility, and conductivity
🗑
|
||||
| Chemical Properties | the ability of a substance to react with other substances
🗑
|
||||
| Periodic Table | a chart of elements arranged by their atomic number (the number of protons in their nucleus)
🗑
|
||||
| Periods | rows that begin with atoms containing one valence electron and end with atoms with a complete outer shell containing 8 electrons
🗑
|
||||
| Groups | members have similar chemical and physical properties
🗑
|
||||
| Solids | atoms, ions, and molecules are locked into fixed positions, giving the substance a fixed volume and shape
🗑
|
||||
| Liquids | when energy is transferred to a substance, its particles start to move around melting the solid, this has volume, but no fixed shape
🗑
|
||||
| Gases | if more heat is applied to a liquid, its particles will move more rapidly, breaking all connections and turn into this
🗑
|
||||
| Acid | a special type of compound that forms hydrogen ions when dissolved in water, they taste tart or sour
🗑
|
||||
| Base | a special type of compound that forms hydroxide ions in water, they taste bitter and are slippery
🗑
|
||||
| Acid/Base Reactions | combine to produce a water and a salt
🗑
|
||||
| Displacement | a change in an object's position
🗑
|
||||
| Distance | the total length moved by the object
🗑
|
||||
| Velocity | the rate and direction an object moves
🗑
|
||||
| Acceleration | the change in an object's velocity (measured m/s/s)
🗑
|
||||
| Momentum | mass multiplied by velocity
🗑
|
||||
| Friction | a force from rubbing surfaces that opposes motion
🗑
|
||||
| First Law of Motion | also called the Law of Inertia- an object at rest stays at rest, and an object in motion stays in motion at the same velocity unless an unbalanced force acts upon it
🗑
|
||||
| Second Law of Motion | the net force acting on a body equals its mass times acceleration
🗑
|
||||
| Third Law of Motion | for every action, there is an equal and opposite reaction
🗑
|
||||
| Energy | the ability to do work
🗑
|
||||
| Kinetic Energy | the energy of motion
🗑
|
||||
| Potential Energy | stored energy
🗑
|
||||
| Law of Conservation of Energy | energy can change its form, but its total quantity is always conserved
🗑
|
||||
| Thermal Energy | a form of kinetic energy, basedon the vibrations and movements of atoms and molecules
🗑
|
||||
| Temperature | a measure of the average kinetic energy of an object's particles; the higher the temperature, the greater their movement
🗑
|
||||
| Heat | a transfer of energy from an object with a higher temperature to one with a lower temperature
🗑
|
||||
| Nuclear Fission | splitting of nuclei of large atoms, releasing nuclear energy
🗑
|
||||
| Nuclear Fusion | the joining together of nuclei of small atoms- hydrogen into helium- also releasing nuclear energy
🗑
|
||||
| Chain Reaction | when a nucleus splits, its extra neutrons split other nuclei, releasing more energy and nuclei, splitting even more nuclei
🗑
|
||||
| Nuclear Reactions OR Conservation of Mass and Energy | in nuclear reactions, small amounts of matter are converted into large amounts of energy
🗑
|
||||
| Mechanical Waves | seismic, water, or sound passing through a medium; particles of medium pass along the energy of the wave
🗑
|
||||
| Electromagnetic Radiation | can pass through some forms of matter but do not require it; can pass through a vacuum or outer space; includes invisible waves as well as visible light
🗑
|
||||
| Refraction | a wave bends when passing through a different medium
🗑
|
||||
| Reflection | waves bouncing back
🗑
|
||||
| Diffraction | waves bending around
🗑
