A) \[458\text{ }J\text{ }k{{g}^{-1}}{{K}^{-1}}\]
B) \[1232\text{ }J\text{ }k{{g}^{-1}}{{K}^{-1}}\]
C) \[916\text{ }J\text{ }k{{g}^{-1}}{{K}^{-1}}\]
D) None of these
Correct Answer: D
Solution :
Heat loss = Heat gain |
\[192\times S(100-21.5)=(128\times 0.394+240\times 4.2)\] |
\[(21.5-8.4)\] |
\[192\times 78.5\times S=1058.432\times 13.1\] |
\[S=0.91995\text{ }J/g\text{ }{{K}^{-1}}\] |
\[S=919.95\text{ }J/kg\text{ }{{K}^{-1}}\] |
