Based on the law of conservation of energy, which statement is false

energy is lost when machines don’t work right.

we can’t add more energy to the universe.

we can’t destroy energy that exists in the universe.

energy changes from one form to another.

Energy is lost when machines don’t work right.

Explanation:

As per law of conservation of energy we can say that energy will convert from one form to another form in an isolated system but the total energy of the system will always remain conserved.

So here in isolated system such as universe we can say that the total energy of the universe is conserved and neither we can add more energy to it nor we can destroy that present amount of energy

Total energy of the system or universe is conserved

So correct answer will be

Energy is lost when machines don’t work right.

This is false statement because machines are used to give more output and hence they is meant to give output work for given input energy
