16.3: Mass, Energy, and the Theory of Relativity
Converting Matter into Energy. The remarkable equivalence between matter and energy is given in one of the most famous equations: E = m c 2 E = m c 2. In this equation, E stands for energy, m stands for mass, and c, the constant that relates the two, is the speed of light (3 × 10 8 meters per second) (3 × 10 8 meters per second).Note that mass is a measure of the quantity of …

Scientists soon realized that the conversion of mass into energy is the source of the Sun''s heat and light. With Einstein''s equation of E = mc 2, we can calculate that the amount of energy radiated by the Sun could be produced by the complete conversion of about 4 million tons of matter into energy inside the Sun each second. Destroying 4 ...

Solar energy reaching Earth: 1400 Watts/m 2 (solar constant) Total Luminosity of the Sun equivalent to the energy flow through a sphere surrounding the Sun. This is an example of the inverse square law. The surface area of this sphere is 2.8 x 10 23 m 2; So, the total luminosity is: 1400 Watts/m 2 x 2.8 x 10 23 m 2 = 4 x 10 26 Watts
16.2 Mass, Energy, and the Theory of Relativity
At the temperatures inside the stars with masses smaller than about 1.2 times the mass of our Sun (a category that includes the Sun itself), most of the energy is produced by the reactions we have just described, and this set of reactions is called the proton-proton chain (or sometimes, the p-p chain). In the proton-proton chain, protons collide directly with other protons to form helium …

What type of reaction occurring inside the sun produces the solar energy?
Hint: Solar energy is the energy we get from the sun. Sun is a star, producing solar energy continuously from billions of years and will continue to do so for upcoming millions of years. Hence there must be an enormous amount of energy present within the sun or there must be a reaction going on. Only nuclear reactions can produce this much amount of energy.
