The pressure is to be raised from atmospheric to 7 psi (4.83 bar). The process is adiabatic, and the volume is constant and unknown. The effect on air temperature and air density are required. Ie, temperature rise and density increase.© BrainMass Inc. brainmass.com March 4, 2021, 9:16 pm ad1c9bdddf
Here the process is adiabatic- means there is no heat exchange between the system and the surroundings. The system is assumed to be closed, thermally and mechanically
The initial pressure of the system P1 =1 atmosphere =1 bar
Final pressure P2 =4.83 bar
The expert determines the pressure's effects on temperature/density in an adiabatic process.
