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:

a. the total mass in the system
b. the force of gravity
c. the total energy
d. none of the above

None of the above

Explanation:

When energy is converted from one form to another in a chemical or physical change, none will change. This is due to the law of conservation of energy. It states that the total energy of the system remains constant. It only changes energy from one form of energy to another. So, the correct option is (d) "none of the above".

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
