Term | Definition |

Physical Properties | A characteristic of matter that can be observed or measured and can be changed without changing the mater itself. |
Matter | anything that has mass and takes up space |
Mass | The amount of matter an object has. |
Weight | The measure of the amount of gravity acting on an object's mass. |
Volume | The amount of space taken up by matter. |
Relative Density | floating or sinking when compared to water, greater (more) density than water (sinks) and less density (floats) |
Solubility | The ability of a substance to dissolve in another substance, such as sugar dissolving in water. |
Solid | A state of matter in which the substance has a set shape and size. |
Liquid | A state of matter in which the substance takes the shape of the container and has an unchanged volume when poured from one container to another. |
Gas | A state of matter in which the substance expands to take both the shape and the volume of its container |
Conductor | a substance or object that allows energy to flow through it easily. |
Dissolving | the process of forming a mixture of a substance broken down into small pieces and spread evenly throughout a liquid (water). |
electrical energy | energy that is absorbed or delivered by an electric circuit |
insulator | A substance or object that does not allow energy to flow through it easily. |
Magnetism | An attracting or repelling force that causes magnetic material to move. |
Melting | the process of changing a substance from a solid to a liquid by adding thermal energy. |
Metric System | The decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass. |
Mixture | A combination of two or more substances that can be easily separated in some physical way. |
Solution | A type of mixture in which the particles of one or more substances are dissolved (uniformly dispersed throughout) in another substance. |
States of Matter | The forms matter can take, such as solid, liquid, and gas; sometimes called phases of matter |
Thermal Energy | Energy related to the temperature of an object or a substance |
