Coal contains only minute quantities of radioactive materials, yet there is more environmental radiation surrounding a coal-fired power plant than a fission power plant. This indicates that ________.
 
  A) the coal-fired power plant's radiation shields need to be strengthened
  B) the coal-fired power plant has been contaminated
  C) the coal-fired power plant contains none of the radiation it releases
  D) the news media is biased in its coverage

Question 2

Why does transforming water from 100C liquid to 100C gas require much more energy than to raise the temperature of the same amount of water from absolute zero all the way to 100C liquid?
 
  A) While water is in the solid phase, it is only necessary to impart energy to the water molecules themselves. Once in the liquid phase much more heat is required to impart sufficient energy to the molecules because there is more volume present.
  B) False It does not require more energy to transform water from 100C liquid to 100C gas than to raise the temperature of the same amount of water from absolute zero all the way to 100C liquid.
  C) Transforming water from 100C liquid to 100C gas requires breaking the hydrogen bonds between the liquid molecules.
  D) The amount of heat required to raise the temperature of the water or transform its phase is directly proportional to the densities of the water molecules involved. Obviously, driving liquid water to the vapor will drastically change its density.
