Chapter 11, Problem 11.4A

APPLY 11.4 What is the sign and magnitude of q when 10.0 g ofliquid water at 25 °C cools and freezes to form ice at —10 °C? The freezing point of water is 0°C and $C_{\text{m}}[{\text{H}}_{\text{2}}\text{O}\left(l\right)\text{]}=\text{75}.\text{4 J}/\left(\text{mol•}°\text{C}\right)$ , $\Delta H_{\text{fus}}=+\text{6}.0\text{1 kJ}/\text{mol}$ , $C_{\text{m}}\left[{\text{H}}_{\text{2}}\text{O}\left(s\right)\right]=\text{36}.\text{6 J}/\left(\text{mol•}°\text{C}\right)$ .
