Question

3. Which statement about nuclear fission is correct? (1 point)

A. Nuclear fission provides energy for the sun and most U.S. nuclear power plants.

B. Nuclear fission produces massive amounts of energy but requires special containment and a

temperature of millions of degrees Celsius.

C. The fission process can be manipulated in a reactor via the use of control rods, and the energy

released is used for generating electricity.

D. Fission is the process used to produce energy both in nuclear power plants and in atomic bombs

E. All of these statements are correct.

F.

Only b, c, and d are correct.

G. Only c and d are correct.

Answer 1

Statement A: Sun gets its energy from nuclear fusion not fission. Nuclear fission is an in-research topic and has future applications in electricity provider but right now it is in its beginning stages.

Statement B: Fission reaction produces high amount of energy but still the temperatures cannot reach a million ^oCelsius. Fission temperatures can reach near maximum of 1000 ^oCelsius. Nuclear fusion does reach million degree Celsius.

Statement C: This statement is correct as the control rods are used in nuclear reactors to control the fission rate of the radioactive species.

Statement D: This statement is also correct. Nuclear powerplants undergo nuclear fission and atomic bomb is also a nuclear fission bomb.

Hence, Correct option: G. Only C and D are correct.
