Question | Answer |
This is a temperature where the vapor pressure of a liquid equals the atmospheric pressure. | Boiling Point |
Energy stored in chemical bonds of molecules. | Chemical Energy |
This is the process of matter changing from a gaseous state to a liquid state. | Condensation |
This is heat or electrical transfer by contact. | Conduction |
This law states that, in any process, energy is neither created nor destroyed. It can only be converted from one form to another. | Conservation Of Energy |
This is heat transfer due to differences in density. | Convection |
This is a measure of mass per unit volume. | Density |
Energy created by the flow of electrons through a conductor. | Electrical Energy |
The capacity for doing work. It may be transformed from one form to another. | Energy |
This is the process of matter changing from the liquid to the solid state. | Freezing |
This is the phase of matter with no fixed shape or volume. | Gas |
This is the period of time it takes for a radioactive sample to decay to half of its original amount. | Half-Life |
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. | Heat |
Atoms of the same element with varying number of neutrons. | Isotope |
This is energy of motion. | Kinetic Energy |
Energy in the form of electromagnetic radiation. Most often associated with a wavelength that is visible to the eye. | Light Energy |
This is the phase of matter with no fixed shape but fixed volume. | Liquid |
The energy transferred by a force to a moving object. | Mechanical Energy |
This is a group of protons and neutrons in the center of all atoms. | Nucleus |
This is what occurs when matter transitions between solid, liquid and gas. | Phase Change |
Composition of matter which depends on temperature. | Phase Of Matter |
Heat transfer by electromagnetic waves. | Radiation |
Spontaneous disintegration of a radionuclide accompanied by the emission of alpha or beta particles or gamma rays. | Radioactive Decay |
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 into an atom of a different element. | Radioactivity |
This is the phase of matter with fixed shape and volume. | Solid |
Random kinetic energy possessed by objects in a material at finite temperature. An object that feels hot has a lot of this. | Thermal Energy |
A change of state from liquid to gas. | Vaporization |
