Q^6. The term h₀ represents the amount of energy needed to vaporize a unit mass of saturated liquid at a specified temperature or pressure. It can be determined from h₀ = h₀ - h₁.
a) Is it true that it takes less energy to vaporize 1 kg of saturated liquid water at 100°C than it would at 120°C? Substantiate your answer using **values** from Table A- 4. **(8)**
b) Based on your result on (a), does vaporization energy increase at higher temperature or decreases at higher temperature? **(2)**

Step 1:I apologize, but the table you referenced is not fully visible in the image.
Without the specific values from Table A- 4, I cannot complete the precise calculations. However, I can guide you through the problem-solving approach:
Step 2:: Understanding the Problem
- The problem asks about the energy ($$h_{0}$$) needed to vaporize 1 kg of saturated liquid water at different temperatures
- We need to compare the vaporization energy at 100°C and 120°C
Step 3:: Defining the Equation
- $$h_{f}$$ is the enthalpy of saturated liquid
Where:
Step 4:: Recommendation
To solve this problem accurately, I would need:
Step 5:
The specific values for $$h_{g}$$ and $$h_{f}$$ at 100°C and 120°C from Table A-4
Step 6:
To calculate $$h_{0}$$ for each temperature
Step 7:
Compare the values to determine which requires more energy Without the table values, I cannot provide the definitive solution. Would you be able to share the specific values from Table A- 4?
Final Answer
Compare the values to determine which requires more energy Without the table values, I cannot provide the definitive solution. Would you be able to share the specific values from Table A- 4?
