A rigid tank contains 5 kg of an ideal gas at atm and 40° C. Now valve is open, and half of mass of the gas is allowed to escape. If the final pressure in the tank is 1.5 atm, what is the final temperature in the tank?© BrainMass Inc. brainmass.com October 16, 2018, 7:44 pm ad1c9bdddf
The solution provides detailed explanations and instructions for the problem.
Macroscopic Description of an Ideal Gas
A rigid tank contains 0.40 mol of oxygen (02). Determine the mass (in kg) of oxygen that must be withdrawn from the tank to lower the pressure of the gas from 40 atm to 25 atm. Assume that the volume of the tank and the temperature of the oxygen are constant during this operation.
