Answer:
[tex]\displaystyle C = 142\text{ } \frac{J}{^\circ C}[/tex]
Explanation:
We can utilize the heat capacity formula:
[tex]\displaystyle q = C\Delta T[/tex]
Where q is the heat energy, C is its heat capacity, and ΔT is the change in temperature.
By substitution, q = 3711 J and ΔT = 26.1 °C. Hence:
[tex]\displaystyle \begin{aligned} (3711 \text{ J}) & = C(26.1\text{ } ^\circ\text{C}) \\ \\ C & = 142\text{ } \frac{J}{^\circ C}\end{aligned}[/tex]
Hence, the heat capacity of the substance is about 142 J per degrees Celsius.
