What do r and p most likely represent? a.) r represents chemical energy, p represents thermal energy b.) r represents thermal energy, p represents chemical energy c.) r represents potential energy, k represents electrical energy d.) r represents electrical energy, k represents potential energy

Answer is: A.) R represents chemical energy, P represents thermal energy.

A natural gas stove transforms R energy into P energy.

For example methane is natural gas.

Balanced chemical reaction of methane combustion:

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g) ΔH = -802.3 kJ.

This is exothermic reaction, energy is released in form of heat.

The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another.
