The complete combustion of 1.00 kg of coal releases about 3.0 x 10E7 J of energy. The conversion of 1.00 kg of mass into energy is equivalent to the burning of how many metric tonnes of coal?

Respuesta :

Answer: 0.001 metric tonnes

Explanation:

According to Einstein equation, Energy and mass are inter convertible.

[tex]E=mc^2[/tex]

E=  Energy

m = mass

c= speed of light

Given : Complete combustion of 1.00 kg of coal releases about [tex]3.0\times 10^7 J[/tex] of energy.

Given mass: 1 kg

Converting kg to metric ton using the conversion factor:

1 kg=0.001 metric tonnes

Thus 1 kg of coal would also be equal to 0.001 metric tonnes.
