An ideal monatomic gas is compressed starting at point A in a PV diagram where PA = 100 kPa VA = 1.00 m3 and TA = 300 K. The gas is first compressed adiabatically to state B (PB = 200 kPa). The gas is then further compressed from point B to point C (VC = 0.50 m3) in an isothermal process. Determine VB. Calculate the work done on the gas for the whole process.
