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

Answer 1

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

Answer 2

X: Converts mass into energy

Y: Is controlled by neutron absorption
