Question

Which of the following statements is true about both nuclear fusion and nuclear fission? They occur in the sun. Heavy atoms are split. Two light nuclei combine. Some mass changes into energy.

Answer 1

Answer: D) Some mass changes into energy.

Answer 2

Some mass changes into energy

Explanation

Some mass changes into energy are true about both nuclear fusion and nuclear fission. These both reactions produce large amounts of energy. Nuclear fusion is the process in which two light nuclei combine to form a larger nucleus. On the other hand, nuclear fission is reverse in which a heavy nucleus breaks into two light nuclei. Nuclear decay and transmission are also types of nuclear reactions. The matter is not destroyed in nuclear reactions.
