Select the correct answer. Given the law of conservation of energy, what happens when a 200°C iron bar is placed in thermal contact with a 30°C block of wood? A. Energy leaves the iron bar and enters the wood until the temperatures are equal. B. Energy leaves the wood and enters the iron bar until the temperatures are equal. C. All the energy from the iron bar is transferred to the wood. D. All the energy from the wood is transferred to the iron bar. Reset

"electrical energy" transforms to "thermal energy".hope my answer has you : )

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
