4. Using the data provided and your completed Figure 6.4, answer the following questions: a. Just before sunrise, the temperature is 15°C (59°F) with a specific humidity of 8.5 kg H₂O/kg air. Calculate the relative humidity. Show your work. b. By 10 am, the temperature has risen to 25°C (77°F). Assume that the specific humidity remains at 8.5 kg H₂O/kg air. Calculate the relative humidity. Show your work. c. When the heat of the day strikes at 2 p.m., the temperature has risen to 35°C (95°F). Assume that the specific humidity remains at 8.5 kg H₂O/kg air. Calculate the relative humidity. Show your work. d. Santa Barbara has a temperature of 22°C (70°F) and a relative humidity of 60%. What is the specific humidity of the air?
