the answer to your question is
volume
<span>Some important concepts and facts that will let you to label each statement:
1) Both fusion and fission are nuclear reactions by which atoms change and create energy.
2) Fusion is the kind reaction that occurs in the sun, at extreme high temperatures and pressures.
3) Fusion is the union of two lighter atoms into a larger one.
4) Fission is the division of one atom into two lighter atoms.
5) Fussion creates much more energy than fission and create less radioactive material than fission, but scientist have not found how to control it.
6) Fission is used in nuclear plants to generate power because it can be controlled.
7) Fusion is not used to generate power because the extreme conditions needed and lack of control.
8) Fission reactors use uranium rods to control the chain reactions by absorbing neutrons.
X:
Provides household electricity ---> FISSION
Y: Has rods containing uranium ----> FISSION
Y: Requires high temperature and pressure
-----> FUSION
X: Converts mass into energy ----> FISSION
Y: Does not produce usable amounts of
energy ----> FUSION
Y: Is controlled by neutron
absorption ----> FISSION</span>
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it.
