Draw a T-v diagram of a pure substance including the liquid, vapor, and liquid/vapor region. Using this diagram, explain what happens if a saturated liquid is heated (such that the temperature rises) in a rigid (constant volume) container. Using the same diagram, explain what happens when a saturated vapor is heated (such that the temperature rises) in a rigid container.

6. At 60°C, pure substance A has a vapor pressure of 380 mmHg and pure substance B of 140 mmHg. The mole fraction XB=0.15 is in the range of validity of Henry's law. The partial pressure of B at XB=0.1 is 20 mmHg. (a) What is the vapor partial pressure PB at XB=0.15? Answer: PB=30 mmHg. (b) What would PB be at XB=0.15 if the solution were ideal? Answer: PB=21 mmHg. (c) What is the activity coefficient of B, γB,...

What does the triple point on a phase diagram represent? Select one: a. It represents the conditions under which a substance can exist in two of the three phases in stable form. b. It represents the point at which the distinction between liquid and gas phases becomes unclear. c. It represents the conditions of pressure and temperature under which solid, liquid, and gas all co-exist. d. It represents the point at which the substance undergoes sublimation.
