ALL Matter & Energy
| Question | Answer |
|---|---|
| Solution | made up of solute and solvent |
| Chemistry | the study of the composition of matter and the changes that matter undergoes |
| Volume | the measure of space that matter takes up |
| Mass | the amount of matter(stuff) the object contains |
| Diatomic Elements | elements that are always in pairs: Hydrogen, Iodine, Nitrogen, Chlorine, Bromine, Oxygen and Florine |
| Mixture | a physical blend of two or more components |
| Homogeneous Mixture | a mixture in which equal volumes have the same composition |
| Substance | matter that has a constant composition |
| Heterogeneous Mixture | a mixture in which equal volumes have different compositions |
| Solvent | the "thing" that does the dissolving in a solution |
| Element | a substance that contains only one kind of atom |
| Compound | a substance formed when two different kinds of elements combine in a definite proportion |
| Matter | anything that has mass and takes up space |
| Solute | the "thing" that is dissolved in a solution |
| Liquid | a state of matter in which the volume is definite but the shape will change depending on the container |
| Solid | a state of matter in which shape and volume are both definite |
| Gas | a state of matter in which the volume and shape will change depending on the container |
| Energy | capacity for doing work |
| Potential Energy | stored energy |
| Kinetic Energy | energy an object has because of its motion |
| Temperature | measure of average kinetic energy of particles in matter |
| Crystalline Solid | a solid that is orderly, has a regular geometric pattern |
| Physical Properties | the properties of a substance that can be demonstrated without changing the composition of the substance |
| Chemical Properties | describes how matter will react when it changes into another kind of substance |
| Solubility | Amount of solute that will dissolve in a solvent at a certain temperature |
| Luster | shiny |
