| Question | Answer |
|---|---|
| Matter | anything that has mass and takes up space. |
| Solid | matter with definite shape and volume; has tightly packed particles that move mainly by vibrating. |
| Liquid | matter with a definite volume but not definite shape that can flow from one place to another |
| Gas | matter that does not have definite shape of volume; has particles that can move at high speeds in all directions |
| chemical change | change in which the composition of a substance changes. |
| physical change | change in which the form of an appearance of matter changes, but not its composition. |
| law of conservation of mass | mass is neither created nor destroyed. Mass of substances before a physical or chemical change is equal to the mass after the change. |
| Sublimination | |
| Electron | Negatively charged particles in an atom |
| Weight | the measurement of the force of gravity on an object |
| mass | the amount of matter in an object |
| volume | the amount of space an object |
| element | pure substance. can't be broken down anymore. Examples: oxygen, gold, aluminum. |
| plasma | the 4th state of matter. Requires very high heat |
| atom | the most basic particle of an element. |
| proton | positively charged particle in the center (nucleus) of an atom. |
| neutron | a neutral particle in the center (nucleus) of an atom. |
| displacement | a way to measure volume of irregular objects using a graduated cylinder and water. |
| milliliter | a measurement of volume. Equals one cubic centimeter. |
| amorphous solid | solids where particles are not arranged in a repeating pattern. examples rubber, glass, plastic. |
| nucleus | The center of an atom. Contains protons and neutrons. |
| crystalline solid | particles in this solid are arranged in repeating, three dimentional patterns. Examples salt, sugar, snow, sand |
| viscosity | a liquid's resistance to flow. |
| dynamic | particles that make up matter are said to be |
| gram | a measurement of mass |
