**Problem Statement:** Calculate the absolute entropy of steam, in J/mole-K, if \( H_2O(l) \) has an absolute entropy of 70 J/mole-K. (Hint: write the chemical equation for boiling water and use the Thermodynamic Tables.) --- **Explanation:** To calculate the absolute entropy of steam, we start by considering the phase change of water from liquid to gas: - **Chemical Equation for Boiling Water:** \[ H_2O(l) \rightarrow H_2O(g) \] - **Thermodynamic Tables:** Typically, these tables provide the standard molar entropy values for various substances in different phases. - **Approach:** Use the thermodynamic tables to find the entropy change for the phase transition and then add it to the given entropy of liquid water to find the absolute entropy of steam.
