out of a system. Heat, light, mechanical motion, or electricity might all
be involved in such transfers.

Benchmark 4E The Physical Setting: Energy
Transformations
Grades 9-12, page 86
Different energy levels are associated with different configurations
of atoms and molecules. Some changes of configuration require an input
of energy whereas others release energy.
Benchmark 8C The Designed World: Energy
Sources and Use
Grades 6-8, page 194
Energy can change from one form to another, although in the process
some energy is always converted to heat. Some systems transform energy
with less loss of heat than others.
