Question

Which statements best describe the law of conservation of energy? Check all that apply.

1) The total amount of energy in the universe remains constant.
2) Energy can be created or destroyed.
3) Energy cannot be created or destroyed.
4) Energy can change from one type to another.
5) In a closed, isolated system, energy is conserved.

Answer 1

Answer:

The law of conservation of energy is the preserved form of energy.

Option (1) is correct that is the total amount of energy in the universe remains constant.Because energy is conserved.

Option (3) is correct since, it is conserved so, it can not be created or destroyed.

Option (4) Energy can change from one type to another like mechanical to electrical energy but it will remain conserved.

Option (5) is correct because in closed, isolated system energy is conserved.

Answer 2

Answers:

— The total amount of energy in the universe remains constant.Because energy is conserved.

— Energy it can not be created or destroyed.

— Energy can change from one type to another like mechanical to electrical energy but it will remain conserved.

— In a closed, isolated system, energy is conserved.
