You are responsible for the purchase of oxygen gas which, before use, will be stored at a pressure of 200 atm at 300 k in a cylindrical vessel of diameter 0.2 m and height 2 m. would you prefer that the gas behaved ideally or as a van der waals fluid? the van der waals constants for oxygen are a = 1.36 liters2 · atm· mole– 2 and b = 0.0318 liters/mole.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
