SVEN [57.7K]

The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal is True.

<u>Explanation:</u>

Nuclear Fission is the process in which splitting of a nucleus takes place that releases free neutrons and lighter nuclei. The fission of heavy elements like "Uranium is highly exothermic" and releases "200 million eV" compared to the energy that is released by burning coal which gives a few eV.

In the given example, it is obvious that the energy released from 1 gram of uranium is more than that of the energy released from 3 grams of coal because the amount of energy released during nuclear fission is millions of times more efficient per mass than that of coal considering only \frac{1}{10}^{th} part of the original nuclei is converted to energy.
