Question and Answer

Calculate the energy equivalent of \(1\) g of substance.

Answer

The mass, \(m=1g=10^{-3}\mathit{kg}\)
The speed of light, \(c=3\times 10^8m/s\)
Find the Energy as follows:
\(E=mc^2\)
\(E=10^{-3}\times \left(3\times 10^8\right)^2J\)
\(E=9\times 10^{13}J\)
Hence, if one gram of matter is converted to energy, there will be a release of huge amount of energy.
