Which statements best describe the law of conservation of energy? Check all that apply.The total amount of energy in the universe remains constant.Energy can be created or destroyed.Energy cannot be created or destroyed.Energy can change from one type to another. In a closed, isolated system, energy is conserved.
Answer
A
The total amount of energy in the universe remains constant.
B
Energy can be created or destroyed.
C
Energy cannot be created or destroyed.
D
Energy can change from one type to another.
E
In a closed, isolated system, energy is conserved.
Explanation
The law of conservation of energy says that energy cannot be created or destroyed, so the total amount remains constant in the universe and is conserved in a closed, isolated system. Energy can, however, change from one form to another, such as electrical energy becoming light and heat. Thus, the statement that energy can be created or destroyed is incorrect.
