Find the energy equivalent of 1kg of substance
Answers
Answer:
Explanation:
answer: 9 x 10¹3 J
explanation : mass of substance, m = 1g : 10^-3 kg =
velocity of light, v = 3 x 10^8 m/s
according to Enstien's energy - mass equivalent theory, Mass can be converted into pure energy. it is expressed by E mc²
= 10^-3 × (3 x 10^8)²
= 10^-3 × 9 × 10^16 J
= 9 x 10¹3 J
hence, 9 x 10¹3 J amount of energy is equivalent of 1g of substance.
