2. In a nuclear reactor, 0.20 kilogram of uranium-235 and 0.50 kilogram of plutonium-239 are completely converted to energy. How many joules of energy are produced?
Nuclear Fusion
Nuclear fusion is a type of nuclear reaction. In nuclear fusion, two or more than two lighter atomic nuclei combine to form a heavier nucleus. During this process, an enormous amount of energy is released. This energy is called nuclear energy. Nuclear fusion is the energy source of the sun and stars.
Fusion Bomb
A fusion bomb is also known as a thermonuclear bomb or hydrogen bomb which releases a large amount of explosive energy during a nuclear chain reaction when the lighter nuclei in it, combine to form heavier nuclei, and a large amount of radiation is released. It is an uncontrolled, self-sustaining nuclear chain reaction where isotopes of hydrogen combine under very high temperature to form helium. They work on the principle of operation of atomic fusion. The isotopes of Hydrogen are deuterium and tritium, where they combine their masses and have greater mass than the product nuclei, get heated at high temperatures, and releases energy.

Conversion of Mass to Energy
converted to energy. How many joules (J) of energy are produced?
In a nuclear reactor, 0.15 kilogram (kg) of uranium-235 is completely
1. Read and Understand
What information are you given?
Mass = m = 0.15 kg
Speed of light = c = 300,000,000 m/s = 3 × 108 m/s
2. Plan and Solve
What unknown are you trying to calculate?
The amount of energy produced = E = ?
What formula contains the given quantities and the unknown?
E = mc2
Replace each variable with its known variable and known value.
E = (0.15 kg)(3.00 × 108 m/s)²
E = 1.35 x 10¹6 kg-m²/s² = 1.4 x 1016 J
3. Look Back and Check
Is your answer reasonable?
Yes, the calculated number is quite large compared to the mass, and the units
indicate energy.
