Fission and fusion reactions
A)convert a tiny amount of the mass of the nuclear materials to energy.
B)convert energy to the mass of the nuclear materials.
C)release energy without a change in the mass of the nuclear materials.
D)invest energy to generate nuclear materials.

Question

Quizplus · Accepted Answer

Both fission and fusion reactions involve the conversion of a small amount of mass into energy, as described by Einstein's famous equation E=mc². This release of energy is what makes these reactions useful for things like nuclear power and nuclear weapons. Option B is incorrect because it implies the opposite of what actually happens, and option C is incorrect because there is a change in mass, albeit a very small one. Option D is incorrect because it doesn't make sense to invest energy to generate nuclear materials; rather, nuclear materials are created naturally through various processes.
