A sample of a monatomic ideal gas at 1.00atm and 25 degree celsius expands adiabatically and reversibly from 5.02 L to 12.2 L. Calculate the final temperature and pressure of the gas, the work assoiated with this process, and the change in internal energy.
Calculate the entropy change of the surroundings associated with this heat transfer. Assume the weight of an average adult is 80.0 kg.
There are two common polymorphs of zinc sulfide: cubic and hexagonal. Based on the analysis of Madelung constants alone, predict which polymorph should be more stable.
