Calculate the energy equivalent of 1 gram of substance
Answer:
In the context of energy equivalent, when we talk about the energy released from matter, we often refer to Einstein’s famous equation, E=mc^2. This equation states that energy (E) is equal to mass (m) times the speed of light (c) squared. Therefore, to calculate the energy equivalent of 1 gram of substance, we need to use this equation.
Given that the mass of the substance is 1 gram, which is equal to 0.001 kilograms (since 1 gram = 0.001 kg), and the speed of light is approximately 3 x 10^8 meters per second, we can plug these values into the equation.
E = (0.001 kg) x (3 x 10^8 m/s)^2
E = 0.001 kg x 9 x 10^16 m^2/s^2
E = 9 x 10^13 Joules
Therefore, the energy equivalent of 1 gram of substance is approximately 9 x 10^13 Joules according to Einstein’s mass-energy equivalence principle.
