Answer

Here's how to calculate the change in temperature:<br /><br />1. **Formula:** The formula relating heat energy (Q), mass (m), specific heat capacity (c), and change in temperature (Δt) is: Q = mcΔt<br /><br />2. **Specific Heat of Water:** The specific heat capacity of water is 4.18 kJ/kg°C (this value should be on your data sheet).<br /><br />3. **Rearrange the formula:** To solve for Δt, rearrange the formula: Δt = Q / (mc)<br /><br />4. **Plug in the values:**<br /> * Q = 12.0 kJ<br /> * m = 0.350 kg<br /> * c = 4.18 kJ/kg°C<br /><br />5. **Calculate:** Δt = 12.0 kJ / (0.350 kg * 4.18 kJ/kg°C) <br /> Δt ≈ 8.23 °C<br /><br />Therefore, the change in temperature is approximately $\boxed{8.23}$.<br />
