Question

gazala makes a graphic organizer to compare nuclear fission and nuclear fusion. which labels belong in the regions marked x and y? x: provides household electricity y: has rods containing uranium x: provides household electricity y: requires high temperature and pressure x: converts mass into energy y: does not produce usable amounts of energy x: converts mass into energy y: is controlled by neutron absorption

Explanation:

• Both nuclear fission and nuclear fusion convert mass into energy. So, \(X\) (the common part) can be "Converts mass into energy".
• Nuclear fission is controlled by neutron absorption (e.g., in a nuclear reactor, control rods absorb neutrons to control the fission chain reaction). So, \(Y\) (specific to fission) can be "Is controlled by neutron absorption".
• "Provides household electricity" is mainly from fission (as fusion is not yet harnessed for large - scale commercial electricity production). "Has rods containing uranium" is specific to fission. "Requires high temperature and pressure" is specific to fusion. "Does not produce usable amounts of energy" is incorrect as fission does produce usable energy.

Answer:

X: Converts mass into energy; Y: Is controlled by neutron absorption.
