Savion listed the steps involved when nuclear power plants generate electricity. nuclear reaction occurs. nuclear energy is converted to radiant and thermal energy. heat is used to generate steam. light and heat are released. steam turns turbines. mechanical energy is converted to electrical energy. which best explains how to correct savion’s error?
a. in step 2, change “radiant and thermal ” to “chemical and mechanical.”
b. reorder the steps so that step 4 appears before step 3.
c. reorder the steps so that step 6 appears before step 5.
d. in step 6, change “mechanical” to “thermal.”

Answer is: b.reorder the steps so that step 4 appears before step 3.

The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another.

In this example energy is transformed:

1) from chemical energy to thermal and radiant energy.

2) from thermal energy to kinetic energy.

3) from kinetic energy to electric energy.

Nuclear energy is the energy found in the nucleus of an atom. For example nuclear fission is radioactive decay process in which the nucleus of an atom splits into smaller parts and huge amount of energy is released.
