A $1.0\; g$ sample of substance A at $100^\circ C$ is added to $100\; mL$ of $H_2O$ at $25^\circ C$. Using separate $100\; mL$ portions of $H_2O$, the procedure is repeated with substance $B$ and then with substance $C$. How will the final temperatures of the water compare?

Question

(a) $T_C > T_B > T_A$
(b) $T_B>T_A>T_C$
(c) $T_A>T_B>T_C$
(d) $T_A=T_B=T_C$
