Electric Generator:Turns the chemical energy in fossil fuels to electrical energy
Electrical Energy:the energy of moving electrons
Energy:is the ability to do work
Energy Conservation:a change of one form of energy to another
Energy Efficiency:the percentage of energy put into a system that does useful work
External Combustion:the heat that burns fuel outside the engine
Fission:The process of which the nucleus separates
Fossil fuel:nonrenewable energy formed from the dead remains of dead organisms
Friction:when two forces in contact repel from each other

Insulation:reduces the transfer of electricity, heat, or sound
Internal Combustion:heat engine that burns fuel inside the engine
Kinetic Energy:energy of object due to it's motion
Law of Conservation of Energy:states that energy cannot be created nor destroyed but it can change its form
Light Energy:made by vibrations of electrically charged particles
Mechanical Energy:the amount of work an energy can do because of its kinetic and potential energy
Nonrenewable Resource:a resource that cannot be produced again
Nuclear Energy:can be released by fission or fusion; binds the energy of the atoms nucleus

Radiometer:a device that measures energy from the sun
Renewable Resource:a resource that can be produced again
Sound Energy:shows how a vibrating object transmits energy through the air around it
Specific Heat:the amount of heat required to raise the temperature by one unit
State of Matter:the physical forms of matter which are solids, liquids, gas, and plasma
Temperature:measures how hot or how cold something is
Thermal Conduction:heat being transferred through materials
Thermal Conductivity:the rate at which substance transfers thermal energy
Thermal Energy:all kinetic energy due to the random motion of a particle that make an object
Thermal Energy:The kinetic energy of a substance's atoms
Thermal Expansion:is if the temperature increases then sizes increases
Thermal Insulators:substances that do not conduct thermal energy well
Thermal Pollution:temperature in water increase because of human activity in it and has a harmful effect on quality and ability to support life
