Question

The law of conservation of energy is a statement that : energy must be conserved and you are breaking a law if you waste energy.

the total amount of energy is constant for a closed system.
the supply of energy is limited so we must conserve.
energy can be used faster than it is created.
energy cannot be used faster than it is created.

Answer 1

The law of conservation of energy states that energy cannot be created or destroyed but only transformed or transferred within an isolated system. Thus, the total energy within a closed system remains constant.

Step-by-step explanation:

The law of conservation of energy states that in any physical or chemical process, energy is neither created nor destroyed. This foundational concept in physics implies that the total amount of energy in an isolated system is constant despite the possibility of energy changing forms or being transferred from one part of the system to another.

Applying this principle, the correct statement from the options given to the student would be that the total amount of energy is constant for a closed system. This is because within such a system, energy can only be transformed from one type to another, such as from potential energy to kinetic energy, or transferred between objects or fields, but the overall energy balance does not change.

Answer 2

option B

Step-by-step explanation:

The correct answer is option B

From the option given option B describes law of conservation of energy which is total amount of energy is constant for closed system.

law of conservation of energy stated that energy cannot be created nor be destroyed but it can transformed from one form to another.

rest options are not correct as they does not follow the statement of the energy conservation.
