Question

Which statements describe or apply the principal of conservation of energy? Select all that apply.

Answer 1

Answer:

A, C, and D

Explanation:

The correct options that apply to the principal conservation of energy are A, C, and D.

A is correct because energy can neither be created nor destroyed. However, energy can be transfered from one location to another or be converted from one form to another. Whether transferred to converted, the magnitude remains the same.

C is correct because energy cannot be destroyed but can be transferred or converted. Hence, if a body or a location loses temprature, then the loss is being gained by another body or location.

D is also correct. A closed system is a system that does not exchange matter with its surroundings. Hence, the total energy remains the same within the system.

Answer 2

Answer:

The total energy in a closed system such as Earth stays the same.

Explanation:

The simplest statement of the law of conservation of energy is that energy can neither be created nor destroyed but can be converted from one form to another.

A typical illustration of this principle of conservation of energy is a closed system of which our universe is an important example.

The total amount of energy in the universe is always a constant. Energy lost in one part must be equal to the energy gained on the other part.
