Chapter 10, Problem 20Q

Define critical temperature and critical pressure. In terms of the kinetic molecular theory, why is it impossible for a substance to exist as a liquid above its critical temperature?

1. Does the diagram best describe a crystalline solid, a liquid, or a gas? Explain.  2. In terms of the arrangement and freedom of motion of the molecules, how are the nematicliquid crystalline phase and an ordinary liquid phase similar? How are they different? 3. It often happens that a substance possessing a smectic liquid crystalline phase just abovethe melting point passes into a nematic liquid crystalline phase at a higher temperature.Account for the type of behavior.
Helium condenses to a liquid at 4.224 K under atmospheric pressure and remains a liquid down to the absolute zero of temperature. (It is used as a coolant to reach very low temperatures.) The vapor pressure of liquidhelium at 2.20 K is 0.05256 atm. Calculate the volume occupied by 1.000 mol helium vapor under these conditions and compare it with the volume of the same amount of helium at standard temperature and pressure.
Study the following phase diagram of Substance X. pressure (atm) 1.2- 0.6- 0. 0 solid liquid 200 gas 400 temperature (K) Use this diagram to answer the following questions. Suppose a small sample of pure X is held at 106. °C and 0.5 atm. What will be the state of the sample? Suppose the temperature is held constant at 106. °C but the pressure is decreased by 0.3 atm. What will happen to the sample? Suppose, on the other hand, the pressure is held constant at 0.5 atm but the temperature is decreased by 145. °C. What will happen to the sample?
