Question

when 1 gram of mass is completely converted into energy the amount of energy released is

Answer 1

E=mC^2

Where,

E= energy released or absorbed during reaction

m= mass of particle

C= speed of light or photons= 3*10^8 m/sec

So, using this formulae,

Energy released= [{1*10^(-3)} * (3* 10^8)^2] joules = 9*10^13 joules = 90 TJ.

Answer 2

Given - Mass

Find - Amount of energy released

Solution - The amount of energy released is 9*10¹³ Joules.

The formula to be used for the calculation of energy released is -

E = mc². In the formula, E is the energy released or absorbed, m is mass and c is the speed of light.

Converting mass in kilograms.

Mass = 0.001 kilogram

Keep the values in the formula to find the energy released.

E = 0.001*(3*10⁸)²

E = 9*10¹³ Joules.

Thus, the amount of energy released is 9*10¹³ Joules.
