Chapter 16, Problem 16RQ

To determine

Whether the chain reaction more likely to occur in two separate pieces of uranium-235 or in the same pieces stuck together.

Answer to Problem 16RQ

The chain reaction more likely to occur in same pieces stuck together of uranium-235.

Explanation of Solution

The greater chances for the chain reaction are when the mass of any element is in the larger amount. A chain reaction is self-sustaining when the element reaches its critical mass. This is the method that is used to produce the atom bombs.

First, uranium-235 is kept into the small pieces separately and after locking the target, those small pieces united together to result in the biggest explosion.

Conclusion:

Therefore, the chain reaction more likely to occur in same pieces stuck together of uranium-235.
