Bert works on the giant turbines at a nuclear reactor. Steam moves these turbines to produce mechanical energy which can be transformed into other types of energy. What nuclear technology produces the steam that Bert sees every day?

1. Radiation decay
2. Radiation isotope
3. Nuclear fusion
4. Nuclear Fission

The correct answer is  "c".  it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings. 

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.
