Question

Map Sapling Learning macmilan leaming Determine whether the statements are true or false, and sort them into the appropriate bins True False The more prevalent isotope of uranium, U-238, does not typically undergo fission Chain reactions are self-sustaining events On average, each reaction event causes one or more other reaction events when it absorbs neutrons A subcritical mass is one in which the chain reaction dies out Critical mass is the minimum amount of a substance for which each fission event causes an average of one additional fission event The energy released by the fission of one Chain reactions often occur spontaneously burning of an equivalent mass of gasoline uranium nucleus is very small relative to the in natural uranium deposits The splitting of atomic nuclei Chain reactions are more likely to occur in smaller chunks of uranium than in larger chunks is called nuclear fission.

Explanation / Answer

True False Chain reaction are self-sustainable events U-238 does not perform fission when it absorbs neutrons chain reaction often occurs spontaneously in natural uranium deposits A subcritical mass is one in which the chain reaction dies out The splitting of atomic nuclei is called nuclear fission The energy released by the fission of uranium is very less relative to burning an equivalent mass of gasoline Critical mass is the minimum amount of a substance for which each fission events causes an average of one additional fission events Chain reactions are more likely to occur in the smaller chunks of uranium than in larger chunks
