Question

chemical energy is the energy stored in the chemical bonds that hold molecules together. its a form of potential energy, and can be used when these chemical bonds are altered. consider your digestive system. after a meal, chemicals are released in your body to break down the molecular bonds in the food you ate. this releases the chemical energy that was stored in the food, thus powering your muscles, warming your body and allowing you to move. chemical energy stored in wood can be converted to thermal energy by burning the wood.
we feel thermal energy as heat. because the particles that make up all matter are constantly in motion, they always have kinetic energy. thermal energy is the amount of kinetic energy or movement in the particles, atoms and molecules of an object. the faster those particles are moving, the more kinetic energy the object has and the warmer it will feel. for example, the water in a cup of hot coffee has more thermal energy than the same cup of coffee after it has cooled.
how do we get energy from the food we eat?
a the constantly moving molecules in food give us kinetic energy.

Explanation:

The text states that after a meal, chemicals are released in the body to break down molecular bonds in food, releasing the stored chemical energy which powers muscles, warms the body etc. It is not the kinetic - energy of moving molecules in food that gives us energy but the chemical energy stored in food's chemical bonds.

Answer:

The statement in option A is incorrect as we get energy from the chemical energy stored in the food's chemical bonds, not from the kinetic energy of constantly moving molecules in food.
