Question

A system that always has the same amount of energy except when heat is added to it obeys the law of conservation of energy. Is this statement true or false ?
A. True
B. False

Answer 1

Answer:

A. True

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.

Answer 2

A. True, it is because laws don’t break or destroy and doesn’t break apart.
