Document Summary
Energy can neither be created nor destroyed. But it can be converted from one form to another. The first law of thermodynamics - total amount of energy in the universe is constant. But systems within the universe can gain or lose energy. When the vase hits the floor the kinetic energy of the vase was converted to: Motions of pieces of the vase on the floor. Travels at the speed of light (186,000 miles/s) Amount of energy carried by the wave is determined by its wavelength. The full range of wavelengths is called the electromagnetic spectrum. Temperature: average kinetic energy of a collection of molecules. Convection: warm (less dense) regions of a gas or liquid rise. Radiation: matter loses reat by radiation, producing electromagnetic energy. Latent heat transfer: heat transfer associated with phase transitions (melting, freezing, evaporation, condensation) Chemical energy - potential energy associated with the formation or breakage of bonds between atoms.
