Question 10 • Chemistry

Which scenario would adhere to the law of conservation of energy?

Answer
A
Energy is created when water freezes.
B
Energy is destroyed when sugar is burned.
C
Energy is transferred when atoms are rearranged.
D
Energy stays inside molecules permanently.

Explanation

The law of conservation of energy says energy cannot be created or destroyed, but it can be transferred or changed from one form to another. When atoms are rearranged in a chemical reaction, energy may be transferred between the reacting substances and their surroundings. So “Energy is transferred when atoms are rearranged” is the correct scenario. Freezing water and burning sugar do not create or destroy energy.
