Answer

$38.43C^{\circ}$

Work Step by Step

The required temperature can be determined as follows: We know that $Q=mc\Delta T$ This can be rearranged as: $\Delta T=\frac{Q}{mc}$ We plug in the known values to obtain: $\Delta T=\frac{1500}{250\times 4.184}=\frac{750}{523}=1.43C^{\circ}$ Now the final temperature is given as $T_f=T_i+1.43$ $\implies T_f=37+1.43=38.43C^{\circ}$
