A) \[0.0521K\]
B) \[0.0186K\]
C) \[0.521K\]
D) \[1.86K\]
Correct Answer: A
Solution :
: \[\Delta {{T}_{f}}=T_{f}^{o}-{{T}_{f}}=0-(-0.186)={{0.186}^{o}}C\] \[\Delta {{T}_{f}}={{K}_{f}}\times m\] \[\Rightarrow \] \[m=\frac{\Delta {{T}_{f}}}{{{K}_{f}}}=\frac{0.186}{1.86}=0.1m\] \[\Delta {{T}_{b}}={{K}_{b}}\times m=0.521\times 0.1=0.0521K\]You need to login to perform this action.
