Question

Burning coal results in several energy transformations to generate electricity. Which statement is correct about the chemical energy stored in chemical bonds between atoms when coal is burned? (1 point)
It increases the number of atoms.
It helps transform kinetic energy to potential energy.
It converts to thermal energy.
It allows the bonds to form and then break.

Answer 1

It converts to thermal energy.

When coal burns, chemical (bond) energy is released in an exothermic reaction and appears mainly as thermal energy (and some light), as the original bonds break and new bonds (e.g., CO2, H2O) form.
