Question

Choose the correct statement.

a. Usually, when one form of energy is converted to another, no energy is wasted.
b. The total amount of energy in the universe is gradually decreasing.
c. This statement illustrates the first law of thermodynamics.
d. An organism decays after it dies.
e. This statement illustrates the second law of thermodynamics.
f. Potential energy is also known as entropy.

Answer 1

Of all the given statements, the following are all true

• Usually, when one form of energy is converted to another, no energy is wasted
• An organism decays after it dies.
• This statement illustrates the second law of thermodynamics.
• Potential energy is also known as entropy.

Answers: Option A, D, E and F

Explanation:

• Option A says that the energy converts from one to another form but there is no wastage of energy. This is totally justified by the law of energy conservation.
• Option B, says that the total energy in the universe of usable form has been gradually decreasing. It is false as the total amount remains constant.
• Option D, says the organism decaying process after its death, which is also true and can be seen as the conversion of energy forms.
• Option E supports the facts and hence is true.
• Option F, says that the entropy is the potential energy which is explained in second law of thermodynamics.
