energy Flashcards
List the major sources of energy and alternative sources of energy such as solar and wind
Primary energy sources take many forms, including nuclear energy, fossil energy – like oil, coal and natural gas – and renewable sources like wind, solar, geothermal and hydropower.
what is energy
the ability to make things happen (do work )
what is the law of conservation of energy
energy can’t be created or destroyed, it can only be transformed into another form. the total amount of energy remains constant
what is energy transfer
the movement of energy from one place to another
Describe the thermal energy transfer processes of conduction
In CONDUCTION, heat is transferred by particles vibrating.
Describe the thermal energy transfer processes of convection
In CONVECTION, heat energy is carried by the movement of particles of matter.
Describe the thermal energy transfer processes of radiation
In RADIATION, heat is carried directly by electromagnetic waves.
