Evaluate the right answer of the given problem
Problem- Air in a 0.3 m3 cylinder is initially at a pressure of 10 bars and a temperature of 330 K. The cylinder is to be emptied by opening a valve and letting the pressure drop to that of the atmosphere.
Part 1- What will be the temperature and mass of gas in the cylinder if this is accomplished?
i- In a manner that maintains the temperature of the gas at 330 K?
ii- In a well-insulated cylinder?
For simplicity assume, in ii, that the process occurs sufficiently rapidly that there is no heat transfer between the cylinder walls and the gas. The gas is ideal, and C*p=29(J/mol K).
I need experts help to find the temperature and mass of gas in cylinder.
