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.
