**Question 11 of 35** **Data Provided:** - \( C_{\text{liquid}} = 1.45 \, \text{J/mol} \cdot \degree \text{C} \) - \( C_{\text{gas}} = 0.65 \, \text{J/mol} \cdot \degree \text{C} \) - \( T_{\text{boiling}} = 88.5 \, \degree \text{C} \) - \( \Delta H_{\text{vaporization}} = 1.23 \, \text{kJ/mol} \) **Description:** The image shows data needed for a thermodynamics problem involving a phase change from liquid to gas. The heat capacities of the liquid and gas phases, the boiling point temperature, and the enthalpy of vaporization are provided. **Calculator Interface:** A calculator interface is displayed, including a standard numerical keypad and functions for basic calculations. The bottom note suggests additional resources are available. **Considerations for Understanding:** Concepts such as specific heat capacity, boiling point, and enthalpy of vaporization are crucial in solving such problems, typically involving energy calculations during phase transitions.
