The correct answer is A. Transfers energy to another atom or molecule.
Explanation:
In physics, heat is produced by the inner energy of a substance or the transfer of heat from one body to another. In terms of inner energy, this is the result of the collision between particles or atoms. This can be explained as every time a particle or atom collides with others part of the energy of the atom is transferred, and this leads to heat. According to this, heat is conducted when one atom or molecule collied with and transfers energy to another atom or molecule.
