WebSep 25, 2024 · Natural gas: Combustion reaction converts chemical energy into light and heat. Food: Digested to convert chemical energy into other forms of energy used by cells. Cold packs: Chemical energy is absorbed in a reaction. Propane: Burned to produce heat and light. Hot packs: Chemical reaction produces heat or thermal energy. WebConservation of energy implies that the chemical energy stored in food is converted into work, thermal energy, and/or stored as chemical energy in fatty tissue. (See Figure 1.) The fraction going into each form depends both on how much we eat and on our level of physical activity. If we eat more than is needed to do work and stay warm, the ... st andrews ps dundee
