14. The total energy of a blackbody radiation source is collected for one minute and used to heat water. The temperature of the water increases form 20.0 \mbox{ ^oC} to 20.5 \mbox{ ^oC}. If the absolute temperature of the blackbody were doubled and the experiment repeated, which of the following statements would be most nearly correct?
(A) The temperature of the water would increase from 20 \mbox{ ^oC} to a final temperature of 21 \mbox{ ^oC}
(B) The temperature of the water would increase from 20 \mbox{ ^oC} to a final temperature of 24 \mbox{ ^oC}
(C) The temperature of the water would increase from 20 \mbox{ ^oC} to a final temperature of 28 \mbox{ ^oC}
(D) The temperature of the water would increase from 20 \mbox{ ^oC} to a final temperature of 36 \mbox{ ^oC}
(E) The water would boil within the one-minute time period.
