A barrel of oil produces about 5.9 $\times$ 10⁶ kJ of energy. Fission of 235 g of uranium-235 releases 2.1 $\times$10¹⁰ kJ of energy. How many barrels of oil are equivalent to 1 kg of uranium-235?

Question

Quizplus · Accepted Answer

1 kg of uranium-235 releases 2.1 x 10^10 kJ/g x 1000 g = 2.1 x 10^13 kJ. Dividing this by the energy per barrel of oil (5.9 x 10^6 kJ) gives approximately 15,100 barrels.

A Barrel of Oil Produces About 5 ×\times× 106 KJ of Energy
