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:

1. Recall properties of nuclear fission and fusion:

• Both nuclear fission and fusion convert mass into energy (this is the overlap region X).
• Nuclear fission can be controlled by neutron absorption (e.g., in nuclear reactors, control rods absorb neutrons to regulate the reaction), and this is a characteristic of fission (region Y).
• Analyze other options:
• Option 1: Fusion does not provide household electricity (fission in reactors does), and fusion doesn't have uranium rods. Eliminate.
• Option 2: Fusion requires high temp/pressure (not fission), so Y can't be that. Eliminate.
• Option 3: Fusion can produce large energy (e.g., in stars), so Y's "does not produce usable amounts" is wrong. Eliminate.

Answer:

X: Converts mass into energy
Y: Is controlled by neutron absorption (the last option in the list)
