question
when energy is converted from one form to another in a chemical or physical change, which of the following also changes by a measureable amount?
select the correct answer below:
the total mass in the system
the force of gravity
the total energy
none of the above

Explanation:

According to the law of conservation of energy, the total energy in a closed system remains constant during energy conversions. The force of gravity is a fundamental force and doesn't change due to energy conversion in a chemical or physical change. Also, the law of conservation of mass (in non - nuclear reactions) states that the total mass in a system remains constant. So, none of the first three options change by a measurable amount.

Answer:

None of the above
