Document Summary
Astronomy 5. 2: yellow hot is hotter than red hot but not as hot as white-hot. Atom the smallest unit of chemical element consisting of a nucleus containing positively charged protons, no charged and mass same as proton, neutrons and negatively charge electrons. Nucleus central core of an atom containing protons and neutrons that carries a net positive charge. Molecule two or more atoms bonded together. Heat energy stores in a material as agitation/movement among its particles. Temperature a measure of agitation/movement among the atoms and molecules of a material. A number related to average speed of particles, intensity of particle motion. Kelvin temperature temp. scale starting at absolute zero (-273 degrees celsius). Change of 1 kelvin is 1 degrees in. Absolute zero theoretical lowest possible temperature at which a material contains no heat energy that can be extracted. Blackbody radiation radiation emitted by a hypothetical perfect radiator spectrum is continuous and wavelength of maximum emission depends on blackbody"s temperature.
