Answer:

2,354,084.7 J

Explanation:

-We apply the Specific Heat Capacity formula to solve for the heat loss:

[tex]Q=mc\bigtriangleup T[/tex]

where

m is the mass of the substance

Q is the heat loss/gain

c is the substance's specific heat

T is the change in temperature

\Substitute given values in the equation to solve for Q:

[tex]Q=mc\bigtriangleup T\\\\\bigtriangleup T=933.15\ K-298.15\ K=635 \ K\\\\\therefore Q=4110\ g \times 0.902\ J/g\textdegree C\times 635 \ K\\\\=2,354,084.7 \ J[/tex]

Hence, the amount of heat lost is 2,354,084.7 J
