[amp_mcq option1=”as a lubricant” option2=”as a fuel” option3=”as an insulator” option4=”as a moderator” correct=”option4″]<\/p>\n
The correct answer is: D. as a moderator.<\/p>\n
Graphite is a good moderator because it is a good neutron absorber. Neutrons are produced when uranium-235 atoms split, and they need to be slowed down in order to be captured by other uranium-235 atoms. Graphite slows down neutrons by scattering them. This is important because it allows the chain reaction to continue.<\/p>\n
A lubricant is a substance that reduces friction between two surfaces. Graphite is not a good lubricant because it is a solid. Solids do not flow easily, and they can actually increase friction.<\/p>\n
A fuel is a substance that is burned to produce heat. Graphite is not a good fuel because it does not burn easily. It is also not a good source of energy.<\/p>\n
An insulator is a substance that does not conduct electricity. Graphite is a good insulator because it is a poor conductor of electricity. This is important because it prevents the flow of electricity through the reactor core.<\/p>\n","protected":false},"excerpt":{"rendered":"
