**Physical Constants**

The constants for \( \text{H}_2\text{O} \) are shown here:

- **Specific heat of ice:** \( s_{\text{ice}} = 2.09 \, \text{J/(g} \cdot \text{°C)} \)
- **Specific heat of liquid water:** \( s_{\text{water}} = 4.18 \, \text{J/(g} \cdot \text{°C)} \)
- **Enthalpy of fusion** (\( \text{H}_2\text{O(s)} \rightarrow \text{H}_2\text{O(l)} \)): \( \Delta H_{\text{fus}} = 334 \, \text{J/g} \)
- **Enthalpy of vaporization** (\( \text{H}_2\text{O(l)} \rightarrow \text{H}_2\text{O(g)} \)): \( \Delta H_{\text{vap}} = 2250 \, \text{J/g} \)
