Question
1. A perfect gas undergoes compression at constant temperature, which reduces its volume
by 3.08 dm3. The final pressure and volume of the gas are 6.42 bar and 5.38 dm3, respectively. Calculate the original pressure of the gas in (a) bar, (b) atm.
2. Consider an isothermal column of an ideal gas at 25oC. What must be the molar mass of
this gas be if the pressure is 0.80 of its ground level value at (a) 10km and (b) 1km ?
