Physical Properties
Unit 6 Vocabulary
| Term | Definition |
|---|---|
| Property | Characteristics of a substance that can be observed or measured |
| Solubility | Ability of 1 substance to be dissolved in another one |
| Dissolve | When 2 substance mix to form a solution |
| Relative Density | Density of an object compared to the density of water- determines whether it sinks or floats |
| Conductor | Material that conducts or allows energy to pass through easily (sound, heat, electricity) |
| Insulator | Material that does not allow energy to pass through easily (sound, heat, electricity) |
| Physical State | Form of a substance; solid, liquid, or gas |
| Matter | Anything that has mass and takes up space |
| Mass | The amount of matter in an object |
| Thermal Energy | Heat Energy |
| Electrical Energy | Energy from electrons moving through a circuit |
| Evaporate | Physical Change of a liquid to a gas |
| Magnetism | Force of repulsion (pushing) or attraction (pulling) between poles of magnets |
| Mixture | Combination of 2 or more different kinds of matter which keep their own physical properties (easily separated) |
| Ingredient | A single part of a mixture or a solution |
| Solution | Type of mixture in which particles of the 2 substances are evenly mixed (not easily separated) |
| Freezing Point | Temperature at which a liquid changes to a solid (water=0 degrees Celsius) |
| Melting Point | Temperature at which a solid changes to a liquid (water=0 degrees Celsius) |
| Boiling Point | Temperature at which a liquid changes to a gas (water=100 degrees Celsius) |
| Celsius | Temperature scale that sets the freezing point of water at 0 degrees and the boiling point at 100 degrees |
| Condense | Physical change in matter from a gas to a liquid |
| Triple Beam Balance | Tool used to measure mass that features three beams with sliding masses |
| Measurement | Process of using tools to observe an object's physical properties (mass, volume, temperature, length) |
