The molar heat capacity of water at constant pressure, C, is \[75\text{ }J{{K}^{-1}}mo{{l}^{-1}}\]. When 1.0 kJ of heat is supplied to 100 g of water which is free to expand, the increase in temperature of water is:                    [AIPMT 2003]

A)  4.8 K              

B)  6.6 K

C)  1.2 K              

D)  2.4 K

Correct Answer: D

Solution :

\[C=\frac{q}{m({{T}_{2}}-{{T}_{1}})}\]

(Given, that \[C=75\,\,J{{K}^{-1}}\,mo{{l}^{-1}}\],
