finish line in a race? In order to answer all these questions we must
talk about the transformation of one sort of energy into another.
The jet aircraft gets its power from jet turbines. These powerful
jet engines create a high-pressure stream of very hot gases that push the
aircraft forward as they leave the engine. This is an example of heat

in motion. The sun's heat comes to the earth as a form of radiant energy.
When the heat reaches the surface of the earth, it causes the land or seas
to rise in temperature.

The sun is very hot. Infact, the center of the sun can reach
temperatures of up to 27 million degrees Fahrenheit. This is because of
another kind of energy reaction where new substances are continually being
created as others are being destroyed. This reaction is known to us as
the Nuclear Reaction.
Today we are trying to imitate this reaction in improving our energy
supply. Scientists have calculated that the sun has enough fuel to go on
producing energy at its present rate for ...
