NYS ES Topic 5

Energy in Earth's Processes

TermDefinition
Energy the ability to do work
Electromagnetic energy a type of energy that is radiated, or given off, in the form of transverse waves from all matter not at absolute zero
wavelength the distance from one crest of a wave to the next crest
Electromagnetic spectrum any model that shows the types of electromagnetic energy
Energy Refraction energy bent, in their passage through materials of varying density so that the direction of the waves is changed
Energy Reflection energy bounced off the material
Energy Absorption energy taken into the material
Texture the roughness or smoothness of a surface
Conduction the transfer of heat energy from atom to atom or molecule when vibrating atoms or molecules collide
Convection the transfer of heat by movement in fluids - gases and liquids- caused by differences in density within the fluids
Dynamic Equilibrium heat will continue to move from the source to the sink until their energies are equal
Radiation the method by which heat is transferred via electromagnetic waves
Mechanical Energy all the energy of an object or system not related to the individual motions of atoms and molecules
Kinetic Energy an object in motion that has energy
Potential Energy energy related to position or phase
Temperature a measure of the average kinetic energy of the particles of a body of matter - and is not a type of energy
Joules a metric unit of energy or work
Specific Heat the quantity of heat needed to raise the temperature of one gram of any substance one degree celsius
Melting the changing of a solid to a liquid
Solidification (freezing) the changing of a liquid to a solid
crystallization if solidification results in a solid with an ordered pattern of atoms
Evaporation (vaporization) the changing of a liquid to a gas
Condensation the changing of a gas,or vapor, to a liquid
Sublimation the changing of a gas directly to a solid
Nuclear Fusion How the sun gets its energy, by combining the nuclei of smaller elements to form larger elements. Some mass is converted into energy.
Nuclear Decay spontaneous breakdown of large unstable nuclei. Energy is released, but it’s not as much as nuclear fusion.
