That question pissed me off. We learned that moderators slow down neutrons. So how is it elastic?? I just put down what i learned that kinetic energy of the neutrons decreases and gets trannsfered to the moderator atoms but no clue
And what is an ideal gas?
I've since looked it up and a popular definition online is "a theoretical gas that obeys Boyle's Law at all temperatures" or words to that effect. So hopefully I'll get half marks
Why didn't I put that? For some reason I thought the question was asking about the fuel rods, so you didn't have to say it and instead talked about an excess of neutrons, but in retrospect that was really really stupid. What an idiot. That's 1 or 2 marks I easily could have got.
