1
development that meets the needs of the present while protecting the environment for the future
2
the energy required to raise the temperature of one lb of water by 1°F
3
a process in which the amount of a substance has a fixed growth rate, or the change in amount of something is proportional to the amount present
4
an essentially inexhaustible alternative energy source to oil, gas, coal, or uranium used to produce electricity or heat
5
energy stored; a function of the object’s position
