An adiabatic cylinder decreased fitted with a frictionless piston contains 1.00 mol of helium gas at P = 2.50 atm. The external pressure is reversibly decreased until the gas expanded and have a final pressure and temperature of 1.40 atm and 295 K, respectively. Assuming that the gas is a perfect gas, what is the initial temperature? Follow-up: If the cylinder is rigid and the helium gas undergoes an isochoric process with the same initial pressure, final pressure, and final temperature conditions above, what is the initial temperature?

Transcribed Image Text:An adiabatic cylinder decreased fitted with a frictionless piston contains 1.00 mol of
helium gas at P = 2.50 atm. The external pressure is reversibly decreased until the
gas expanded and have a final pressure and temperature of 1.40 atm and 295 K,
respectively. Assuming that the gas is a perfect gas, what is the initial temperature?
Follow-up: If the cylinder is rigid and the helium gas undergoes an isochoric process
with the same initial pressure, final pressure, and final temperature conditions above,
what is the initial temperature?
