Answer:
Explanation:
Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
Answer: Coal: Combustion reaction converts chemical energy into light and heat.
Wood: Combustion reaction converts chemical energy into light and heat.
Petroleum: Can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
Chemical batteries: Store chemical energy to be changed into electricity.
Biomass: Combustion reaction converts chemical energy into light and heat.
Extras: 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.
Photosynthesis: Changes solar energy into chemical energy
