How is thermal energy distributed in most heating systems? A.
convection

B.
conduction

C.
radiation

I think B

Explanation: Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy.
