MPMS What's the Matter
| Term | Definition |
|---|---|
| matter | Anything that has mass and takes up space |
| atom | The smallest particle of an element |
| element | A pure substance that cannot be broken down into any other substances |
| molecule | Created when two or more atoms join together |
| molecule | can be made up of two or more atoms of the same element (like Hydrogen gas = 2 atoms of Hydrogen) or two or more atoms of different elements joining together (like water = 2 atoms of Hydrogen and 1 atom of Oxygen) |
| compound | Created when two or more atoms of different elements join together |
| expand | To get larger in size, volume or quantity |
| Expand | when atoms gain heat energy, they move faster and spread out |
| particles | A very small piece of a part, a tiny portion or speck |
| thermal energy | Heat energy; the motion of molecules in a substance |
| vibrate | A rapid, back and forth motion |
| solid | Particles are closely packed together and vibrate in place |
| Solid | has definite shape and volume |
| solid | can become a liquid when heat is added |
| liquid | Particles touch each other and are packed loosely together |
| liquid | has definite volume but NOT definite shape – takes the shape of container |
| liquid | can become a gas when heat is added |
| gas | Particles in a gas have a lot of thermal energy and are in constant motion |
| gas | Has NO definite volume or shape – take the shape of container when closed |
| gas | Spread out indefinitely when container is not closed |
| density | How much mass is present per given volume |
| Density | = mass divided by volume |
| density | g/cm3 |
| solution | groups of molecules that are mixed up in even distributions |
| solution | solutes are dissolved into solvents to create a _______________ |
| solute | a substance(usually a solid) that is dissolved into another substance |
| solvent | a substance(usually a liquid) that does the dissolving in a solution |
| solubility | The ability of one substance (solute) to dissolve in another substance (solvent) |
