Question:
A gas container is thermally isolated except for a small hole that insures that the pressure inside the container is equal to the atmospheric pressure p0. Initially, the container holds Ni moles of gas at a temperature Ti. The molar specific heat of the gas at constant pressure is cp. The gas is heated up to a temperature Tf by a resistive coil in the cylinder. As the gas temperature rises, some of the gas is released through the small hole. Assume that for the gas remaining in the cylinder the process is reversible and neglect the specific heat of the heater. Determine:
a) The volume V0 of the container.
b) The number of moles ΔN leaving the container in this process.
c) The heat transfer Qif to accomplish this process. Numerical Application:
