A) \[1.2K\]
B) \[2.4\text{ }K\]
C) \[4.8\text{ }K\]
D) \[6.6\text{ }K\]
Correct Answer: B
Solution :
Given, \[C=75\,J{{K}^{-1}}\,mo{{l}^{-1}}\] \[q=1.0kJ\] or \[1000J\] \[C=\frac{q}{m({{T}_{2}}-{{T}_{1}})}\] \[\Rightarrow \] \[75=\frac{1000}{5.55\times \Delta T}\left\{ m=\frac{100}{18}=5.55 \right\}\] \[\therefore \] \[\Delta T=2.4K\]You need to login to perform this action.
