[Maximum number: 3]

This question is in two parts. Part 1 is about energy resources. Part 2 is about thermal physics.
Part 1 Energy resources
Electricity can be generated using nuclear fission, by burning fossil fuels or using pump storage hydroelectric schemes.

Fission of one uranium-235 nucleus releases 203 MeV .

Determine the maximum amount of energy, in joule, released by 1.0 g of uranium-235 as a result of fission.

( 203 MeV is equivalent to) $3.25 \times 10^{-11} \mathrm{~J}$ ;
$6.02 \times 10^{23}$ nuclei have a mass of $235 \mathrm{~g} /$ evaluates number of nuclei;
( $2.56 \times 10^{21}$ nuclei produce) $8.32 \times 10^{10} \mathrm{~J} /$ multiplies two previous answers;
