Though energy cannot be created or destroyed, it can be transferred and transformed. When energy is not in use, it can be stored. Chemical energy is stored in chemical compounds and released through chemical reactions. Think about the ways you have used stored chemical energy. Which are true statements about how chemical energy can be stored and released through chemical reactions? A ... As bike tires roll across the sidewalk, friction is created and they become warmer. B. Solar energy from the sun is absorbed by solar panels, which transforms to chemical energy when it is used as electricity. C. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies. D. Energy stored in organic fuels are used for heat and electricity / When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy. E. Thermal energy causes energy stored in fireworks to convert to kinetic, light, and sound energy.

Correct options are C. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

D. Energy stored in organic fuels are used for heat and electricity / When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

Explanation:

The breakdown of food leads to the release of chemical energy which was first stored in food. This energy is used to drive necessary functions of the body. A series of chemical reactions are involved in the breakdown of food and changing them into useful components for the cell.

Chemical energy is stored in circuits. When the battery is connected to a circuit, the chemical energy gets transferred into electrical energy.
