The Quantity of Heat Absorbed by a Body Is Determined

The quantity of heat absorbed by a body is determined from the formula Q = cmT_f - T_i) . A certain metal has a specific heat c = 0.21 cal/g C^o and a mass m = 25.6 g. The initial temperature is T_i = 34.6^oC, and the final temperature T_f = 54.6^oC. The quantity of heat absorbed is

A) +23 cal.
B) +0.23 cal.
C) +14 cal.
D) +110 cal.
E) +207 cal.
