W/(mk)], sits on a ceramic heating element at 104.0 °c. the diameter of the pan is 18.0 cm, and it contains boiling water at 100.0 °c. (a) if the copper-clad bottom is touching the heat source, what is the temperature at the copper-steel interface? (b) at what rate will the water evaporate from the pan? (latent heat of water evaporation ly-2256 j/g)

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
