Transformations

In a nuclear power plant, uranium atoms are split in a process called “fission.” This releases a tremendous amount of energy. In order to provide this energy to factories and homes, the power plant converts the energy to –

• water

• oil

• natural gas

• electricity

The Theory of the Conservation of Energy states -

• Energy can be created, just not destroyed. It changes its form from one type to another.

• Energy can never be created nor destroyed. It can only change its form from one type to another.

• The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.

• Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.
