Energy Resources!!
15
fuel: is a substance that provides energy such as heat, light, motion, or electricity as the result of a chemical change.
energy transformation: a change from one form of energy to another.
combustion: burning
fossil fuels: are the energy-rich substances formed from the remains of organisms.
hydrocarbons: are chemical compounds that contain carbon and hydrogen atoms.
nucleus: the central core of an atom that contains the protons and neutrons
nuclear fission: is the splitting of an atom's nucleus into two smaller nuclei.
reactor vessel: is the part of the nuclear reactor where nuclear fission occurs.
nuclear fusion: is the combining of two atomic nuclei to produce a single larger nucleus.
efficiency: is the percentage of energy that is actually used to perform work.
insulation: is a layer of material that traps air to help block the transfer of heat between the air inside and outside a building.
energy conservation: means reducing energy use.
hydroelectric power: is electricity produced by flowing water.
solar energy: energy from the sun.
biomass fuels: fuels made from living things
