7) Describe what would happen if one metal were to be heated while in contact. Assume the other metal's temperature does not change, even at the junction. 8) The situation in (7) is unrealistic. Why? 9) How does f(E) play a role in the situation explored in (7)? 10) Due to Ep being a characteristic differing between materials, would you expect materials to 'produce the same number of conduction band electrons for the same change in temperature? 11) Why can the two metals which make up a thermocouple not be the same material? Use your answer from (10) to justify
