Matter
| Question | Answer |
|---|---|
| Matter | anything that has mass, and takes up space |
| Mass | measurement of the amount of matter |
| Volume | the amount of space matter takes up |
| Density | comparing mass and volume |
| Temperature | the amount of energy the molecule's have |
| Physical property | characteristic of a material that can be observed |
| Physical change | a change in size, shape, or state |
| Chemical property | characteristic that shows it can undergo a chemical change |
| Chemical change | a change from one substance to another |
| Solid | has a definate shape and volume |
| Liquid | has an indefinate shape and a definate volume |
| Gas | has an indefinate shape and volume |
| Plasma | has an indefinate shape and volume (superheated gas) |
| Melting | change from solid to liquid |
| Melting point | temperature at which a solid melts |
| Freezing | change from liquid to solid |
| Freezing point | temperature at which a liquid freezes |
| Vaporization | change from liquid to gas |
| Boiling point | temperature at which a liquid vaporizes |
| Condensation | change from gas to liquid |
| Condensation point | temperature at which a gas condenses |
| Sublimation | change from solid to gas |
| Deposition | change from gas to solid |
| Fluid | anything that flows - gas or liquid |
| Buoyancy | the ability of a fluid to exert an upward force on an object immersed in it - this is called buoyant force |
| Archimedes Principle | the buoyant force on an object in a fluid is equal to the weight of fluid it displaced by the object |
| Pascal’s Principle | pressure applied to a fluid is transmitted unchanged throughout the fluid |
| Bernoulli's Principle | as the velocity of a fluid increases the pressure exerted by the fluid decreases |
| Boyle’s Law | as the volume of gas decreases, the pressure of a gas increases, provided the temperature does not change |
| Charles’ Law | as temperature increases, the volume increases, provided pressure remains constant |
| Pressure | force the gas exerts on a given area of the container in which it is contained |
| Volume | three-dimensional space inside the container holding the gas |
| Substance | type of matter with a fixed composition that cannot be separated by physical means |
| Element | substance made up of atoms with the same identity |
| Compound | atoms of two or more elements combined |
| Mixture | material made up of two or more substances that can be separated by physical means |
| Heterogeneous | mixture in which different materials can be easily distinguished |
| Homogeneous | mixture in which two or more substances are uniformly spread out |
| Solution | homogeneous mixture of particles so small that they cannot even be seen with a microscope and will never settle to the bottom of their container |
| Colloid | type of mixture with particles that are larger than those in solution, but still too light to settle out |
| Suspension | heterogeneous mixture containing a liquid in which visible particles settle |
