Unit Test

Question 1

What is the correct order of energy conversions associated with a power plant that uses nuclear fission reactions?

Revolt · Accepted Answer

D: nuclear to thermal to mechanical to electrical

Question 2

In which situation is nuclear power most beneficial?

Revolt · Accepted Answer

C: if there is an isolated location

Question 3

During a heat wave, there is an increased demand for electricity to operate air conditioners. The basic design of a nuclear reactor that generates electricity is shown below.

Revolt · Accepted Answer

B: raise the control rods so that fewer neutrons are absorbed and more can split uranium atoms

Question 4

Why are very high temperatures and pressures required for fusion to occur?

Revolt · Accepted Answer

B: to overcome the repulsion between the protons in the nuclei that join

Question 5

The storage method used for radioactive wastes generated from fission nuclear reactors must be designed to last for how long?

Revolt · Accepted Answer

C: centuries

Question 6

What is the main reason why many nuclear power plants are located near bodies of water?

Revolt · Accepted Answer

C: to have easy access to a coolant for the reactor

Question 7

The image shows a process that releases nuclear energy.

Revolt · Accepted Answer

C: The process must be fission because a large nucleus breaks into smaller nuclei.

Question 8

Which is a concern about mining for uranium?

Revolt · Accepted Answer

B: Dust released in the air could be radioactive.

Question 9

During early research in nuclear energy, why were scientists surprised that the products from splitting a uranium nucleus had less mass than the reactants?

Question 10

Which refers to the continuous release of nuclear energy caused when one fission reaction triggers more nuclear reactions?

Revolt · Accepted Answer

D: chain reaction
