Step 1: Solve using the equation: $$\Delta T = \dfrac{q}{m \cdot s}$$
Step 2: Using a bar problem: $$\dfrac{39,000~J}{} \times \dfrac{1}{830 ~g} \times \dfrac{g^{\circ}C}{4.184 ~J} = {11 ~^{\circ} C \atop ~or~ 1.1 x 10^{1} ~^{\circ} C }$$
Step 3: Significant Figures for the answer: $$\mathrm{q} = 39,000 ~(2 SF) \\ \mathrm{mass} = 830 ~(2 SF) \\ \mathrm{Specific~Heat} = 4.184 ~(4 SF)$$
