    Find the rise in temperature of \[1\,\,kg\] of water if \[1000\,\,J\] of heat is supplied to it.

    A) \[{{\left( \frac{1000}{4186} \right)}^{o}}C\]        

    B)        \[{{\left( \frac{4186}{1000} \right)}^{o}}C\]

    C) \[{{(1000\times 4186)}^{o}}C\]

    D)        \[{{(4186-1000)}^{o}}C\]

    Correct Answer: A

    Solution :

     \[4186\,\,J\] of heat raises the temperature of \[1\,\,kg\] of water by\[{{1}^{o}}C\] \[\therefore \]\[1000\,\,J\]of heat raises the temperature of \[1\,\,kg\] of water by \[={{\left( \frac{1}{4186}\times 100 \right)}^{o}}C\]
