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 highŠpressure stream of very hot gases that push the
aircraft forward as they leave the engine. This is an example of heat

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 ...
