How much energy was transferred during the phase change shown on the cooling curve? Use the phase diagram and table of values below to help you answer the question. ## Cooling Curve for an AlcoholThe graph on the left is titled "Cooling Curve for an Alcohol." It shows temperature measured in Kelvin (K) on the y-axis, plotted against time in minutes on the x-axis. The curve begins at approximately 500 K and shows a decreasing trend. Around 10 minutes, the curve briefly levels off around 400 K before continuing to decrease, indicating a phase change as the alcohol cools.## Phase Diagram of an AlcoholThe graph on the right is titled "Phase Diagram of an Alcohol." It depicts the relationship between pressure (in atm) on the y-axis and temperature (in K) on the x-axis, with both axes not drawn to scale.- **Regions:** The diagram is divided into three distinct regions labeled as solid, liquid, and gas, which represent the states of matter under different conditions.- **Pressure Lines:** The horizontal dashed lines represent specific pressures: - 62 atm marks the upper pressure limit. - 1.00 atm is a standard pressure reference. - 4.2 x 10⁻⁹ atm is the lower pressure limit shown.- **Temperature Points:** Key temperatures are marked: - 150 K is the lower temperature boundary for gas. - 159 K marks the intersection where solid, liquid, and gas coexist, known as the triple point. - 351 K is within the liquid region. - 514 K marks the upper temperature boundary for the diagram.The phase boundaries show how changes in temperature and pressure can result in transitions between solid, liquid, and gas phases. ### Thermodynamic Properties of Water and AlcoholThis table compares the thermodynamic properties of water and alcohol. It provides crucial data for understanding the heat-related behaviors of these two substances.| Property | Water | Alcohol ||---------------------------------------------|-------|---------|| **Heat of Vaporization, \( H_{\text{vap}} \) (J/g)** | 2,260 | 841 || **Heat of Fusion, \( H_{\text{fus}} \) (J/g)** | 334 | 109 || **Specific Heat Capacity of the Liquid, \( c \) (J/g•K)** | 4.18 | 2.46 |#### Explanations:- **Heat of Vaporization (\( H_{\text{vap}} \))**: This is the amount of energy required to convert one gram of a liquid into vapor without a temperature change. Water requires 2,260 J/g, while alcohol needs 841 J/g, indicating that water needs more energy for vaporization.- **Heat of Fusion (\( H_{\text{fus}} \))**: This is the energy needed to change one gram of a solid into a liquid at its melting point. For water, it is 334 J/g, whereas for alcohol, it is 109 J/g. This shows that water requires more energy to melt.- **Specific Heat Capacity (\( c \))**: This is the amount of heat needed to raise the temperature of one gram of a substance by one degree Celsius. Water has a higher specific heat capacity (4.18 J/g•K) compared to alcohol (2.46 J/g•K), meaning water can absorb more heat before changing temperature.

Given mass of alcohol = 10g Melting point = 159 k Boiling point = 351k We have to find out the…
