1) The amount of energy in a system is conserved unless work is done on the system or the system does work on something else. 2) Energy can be converted from one form to another. These features of energy are quantitatively described by the first two laws of thermodynamics. The second law adds that in energy conversions the usefulness of the ...

Evaluate scientific text regarding energy conversions to determine the validity of the claim that although energy cannot be destroyed, it can be converted into less useful forms. Compare different sources of information describing energy conversions to create a coherent understanding of energy flows into, out of, within, and between systems.

Nuclear Energy - stored in the nucleus of an atom, ex: atomic bomb, stars, nuclear power plants. ENERGY CONVERSIONS . Energy can be converted (changed) from one form to another. As it changes from one form to another, some energy can get lost as heat. For example: - Energy conversions in an electric pencil sharpener:

Less desirable forms of energy conversion can occur due to resistance and friction, resulting in thermo energy conversion. Engineers strive to decrease undesirable energy conversions within a system, or energy losses, by planning with system efficiency in mind. Efficiency is the ratio of desired output energy compared to input energy.
