Gazala makes a graphic organizer to compare nuclear fission and nuclear fusion.

a venn diagram with 2 intersecting circles the circle on the left is labeled fusion. the circle on the right is labeled fission. there is a y in the fission circle. there is an x in the intersecting area.

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

The answer is

X: Converts mass into energy

Y: Is controlled by neutron absorption

Explanation:

To maintain a sustained controlled nuclear reaction (nuclear fission), for every 2 or 3 neutrons released, only one must be allowed to strike another uranium nucleus. If this ratio is less than one then the reaction will die out; if it is greater than one it will grow uncontrolled (an atomic explosion). A neutron absorbing element must be present to control the amount of free neutrons in the reaction space. Therefore, nuclear fission is controlled by neutron absorption.

Nuclear fission and fusion both converts mass to energy.

In both reactions total mass of material decreases but the energy comes out from atoms.
