Helium is used in a laboratory as carrier gas for a gas chromatograph. The helium is stored as a pressurized gas in a cylinder initially at 4000 PSIG and is slowly withdrawn from the cylinder. It is important that the helium pressure at the gas chromatograph is constant at 45 PSIG, with a simple single-stage pressure regulator (set at 45 PSIG) installed between the helium cylinder and the chromatograph. In another project in this lab, liquefied ammonia is stored in...

9. One mole of an ideal gas, initially at 300 K, is cooled at constant volume so that the final pressure is one-fourth the initial pressure. Then the Ras expands at constant pressure until reaches the initial temperature. Determine the work done on the gas.

4 (30 points). A rigid tank that is initially evacuated is connected through a valve toa supply line that carries helium at 1 MPa and 300 K. Now the valve is opened, and helium is allowed to flow slowly intothe tank until the pressure reaches IMPa P2). The final temperature and mass of the helium gas in the tank are: T2 300 K and m2 1 kg. Determine the direction (Is heat transferred to or from the tank?) and amount...

A 16.0 L helium tank is pressurized to 22.0 atm. When connected to this tank, a balloon will inflate because the pressure inside the tank is greater than the atmospheric pressure pushing on the outside of the balloon. Assuming the balloon could expand indefinitely and never burst, the pressure would eventually equalize causing the balloon to stop inflating. What would the volume of the balloon be when this happens? Assume atmospheric pressure is 1.00 atm. Also assume ideal behavior and...
