| Chemical Energy | Energy stored in chemical bonds of molecules. |
| Conduction | This is heat or electrical transfer by contact. |
| Density | This is a measure of mass per unit volume. |
| Electrical Energy | Energy created by the flow of electrons through a conductor. |
| Energy | The capacity for doing work. It may be transformed from one form to another. |
| Gas | This is the phase of matter with no fixed shape or volume. |
| Half-Life | This is the period of time it takes for a radioactive sample to decay to half of its original amount. |
| Heat | The transfer of thermal energy between two bodies which are at different temperatures. The SI unit for this is the Joule. Generally considered the raising of temperature due to thermal energy. |
| Isotope | Atoms of the same element with varying number of neutrons. |
| Kinetic Energy | This is energy of motion. |
| Light Energy | Energy in the form of electromagnetic radiation. Most often associated with a wavelength that is visible to the eye. |
| Liquid | This is the phase of matter with no fixed shape but fixed volume. |
| Matter | This is anything with mass that occupies space. |
| Mechanical Energy | The energy transferred by a force to a moving object. |
| Nucleus | This is a group of protons and neutrons in the center of all atoms. |
| Phase of Matter | Composition of matter which depends on temperature. |
| Potential Energy | Energy that is stored. |
| Radiation | Heat transfer by electromagnetic waves. |
| Radioactive Decay | Spontaneous disintegration of a radionuclide accompanied by the emission of alpha or beta particles or gamma rays. |
| Radioactivity | The spontaneous emission of energy and/or matter from the nucleus of an unstable atom. As a result of this emission, the atom may be converted, or decay, into an atom of a different element. |
| Solid | This is the phase of matter with fixed shape and volume. |
| Temperature | This is the measure of intensity of heat in degrees, reflecting the average kinetic energy of the molecules. |
| Thermal Energy | Random kinetic energy possessed by objects in a material at finite temperature. An object that feels hot has a lot of this. |
| Transformation | Process of changing from one form of energy to another. |
| Volume | This is the amount of 3-dimensional space occupied by an object, expressed in length units cubed (in3 and cm3). |
