Question
A gas stove burns propane and oxygen to produce carbon dioxide and water, thereby heating a home (i.e., the surroundings). Where is the source of the heat coming from?
A. The gases formed absorb heat and distribute it throughout the home
B. The formation of carbon dioxide and water releases heat energy
A. The gases formed absorb heat and distribute it throughout the home
B. The formation of carbon dioxide and water releases heat energy

The correct answer is:
**B. The formation of carbon dioxide and water releases heat energy.**
When propane (C3H8) burns in the presence of oxygen (O2), it undergoes a combustion reaction that releases heat. This heat is a result of the exothermic reaction where chemical bonds in propane and oxygen are broken, and new bonds are formed in carbon dioxide (CO2) and water (H2O). The energy released in this process is what heats the home.
