Term | Definition |
Homogeneous Mixture | a mixture in which substances are evenly distributed throughout the mixture |
Substance | a single kind of matter that is pure, meaning it always has a specific makeup- or composition- and a specific set of properties |
Mixture | Made of two or more substances- elements, compounds, or both- that are together in the same place but not chemically combined |
molecules | groups of two or more atoms held together by chemical bonds |
Chemical Property | a characteristic of a pure substance that describes its ability to change into different substances |
Chemical bond | A force of attraction between two atoms |
Heterogeneous Mixture | a mixture in which pure substances are unevenly distributed throughout the mixture |
Chemical Formula | Shows the elements in the compound and the ratio of atoms |
Atom | the basic particle from which all elements are made |
Element | a pure substance that cannot be broken down into any other substances by chemical and physical means |
Chemistry | the study of the properties of matter and how matter changes |
Solution | an example of a homogeneous mixture; forms when substances dissolve |
Matter | anything that has mass or takes up space |
Physical Property | a characteristic of a pure substance that can be observed without changing into another substance |
Compound | a pure substance made of two or more elements chemically combined in a set ratio |
Volume | the amount of space that matter occupies |
International System of Units (ISU) | the system of units (SI) used by scientists to measure the properties of matter |
Mass | the measurement of the amount of matter in an object |
Density | Relates the mass of a material in a given volume |
Weight | a measurement of the force of gravity on you |
Endothermic Change | a change in energy in which energy is taken in |
Physical Change | any change that alters the form or appearance of matter but does not make any substance in the matter into a different substance |
Chemical change | a change in matter that produces one or more new substances |
Law of Conservation of Matter | the fact that matter is not created or destroyed in any chemical or physical change |
Energy | the ability to do work or cause change |
Temperature | a measure of the average energy of random motion of particles of matter |
Thermal Energy | the total energy of all the particles of matter |
Exothermic change | a change in which energy is given off |
Kinetic energy | the energy of matter in motion |
Potential Energy | the energy an object has because of its position |
