Answer
Here's how to calculate the change in temperature:<br /><br />1. **Find the specific heat capacity of water:** The specific heat capacity of water is 4.18 kJ/kg°C (this value should be provided in a data sheet or can be easily looked up).<br /><br />2. **Use the formula for heat transfer:** The formula relating heat transfer (Q), mass (m), specific heat capacity (c), and change in temperature (Δt) is: Q = mcΔt<br /><br />3. **Rearrange the formula to solve for Δt:** Δt = Q / (mc)<br /><br />4. **Plug in the values:** Δt = 12.0 / (0.350 * 4.18)<br /><br />5. **Calculate:** Δt ≈ 8.196<br /><br />Therefore, the change in temperature is approximately 8.20. Since the question specifically states to *not* include units, the answer is simply **8.20**.<br />
