Burning wood in a fireplace is an example of what kind of energy conversion? o a. chemical potential energy converting to heat energy o b. gravitational potential energy converting to heat energy o c. kinetic energy converting to chemical potential energy o d. heat energy converting to kinetic energy

A. because the wood is stored chemical energy and it is converting into heat energy

Chemical potential energy converting to heat energy.

Explanation:

Burning of wood in a fire place or burning of any other compound in presence of oxygen involves combustion. During combustion there is breaking and making of bonds as combustion is a chemical reaction.

For example:

Combustion of carbon gives carbon dixoide:

Combustion is an exothermic reaction, it releases large amount of energy.

Thus in all we are converting the chemical energy of a substance to heat energy during combustion.

Hence combustion involves Chemical potential energy converting to heat energy.

so what is the problem with your lab report and whats the subject of the lab report? i will you
