The heat required to raise the temperature of a substance is given by the formula

Q = C\( \times \)m\( \times \)\(\Delta \) T,where 鈥淐鈥� is the specific heat of the substance, 鈥渕鈥� is the mass of the substance, and 鈥溾垎T鈥� is the change in the temperature of the substance.

We know from the given details that:

\(\Delta \)T = \(\)\({T_{final}} - {T_{initial}} = {89.6^0}C - {23.2^0}C = {66.4^0}C\)

m = 44.7 g

Q = 2110 J

By putting the values above in the equationQ = C 脳 m 脳 鈭� T, we get:

2110 = 44.7\( \times \)66.4\( \times \)C.

\(\begin{array}{c}C = \frac{{2110}}{{44.7 \times 66.4}}\\ = 0.710\frac{J}{{{g^0}C}}\end{array}\)

Thus, the specific heat of the substance is 0.710\(\frac{J}{{{g^0}C}}\).

The specific heat of a substance is a constant value. If the value of specific heat gets matched with the table 5.1, it most likely resembles silicon (Si).
