Calculate the amount of energy needed to convert 17.1 g of water at 35.0 °C to steam at 100.0°C. (q20)
Question 6 (10 pts) Steam distillation can be run more efficiently in some cases using super-heated steam at 1 atm pressure rather than boiling water. By increasing the temperature of the steam beyond the boiling point of water in a controlled fashion, the oil may still be protected from degradation while increasing its contribution to the vapor composition, making the process more efficient. At 150 °C, linalyl acetate exerts a vapor pressure of 93 torr. If a steam still were...
