Which is not a reason that water is used to store spent fuel rods from nuclear power plants? a. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. b. water cools the spent rods. water acts as a radiation shield to reduce the radiation levels. c. water increases the speed of the chain reaction in the fuel rods.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
