Pressure–volume data for three points along a single quasi-static expansion of one mole of an ideal monatomic gas are given below: A: PA=2.0×105 PaP_A = 2.0\times10^{5}\,\text{Pa}, VA=1.0×10−3 m3V_A = 1.0\times10^{-3}\,\text{m}^3 B: PB=1.26×105 PaP_B = 1.26\times10^{5}\,\text{Pa}, VB=1.6×10−3 m3V_B = 1.6\times10^{-3}\,\text{m}^3 C: PC=9.0×104 PaP_C = 9.0\times10^{4}\,\text{Pa}, VC=2.2×10−3 m3V_C = 2.2\times10^{-3}\,\text{m}^3 (a) Using the data alone, perform one short numerical check to decide whether the process is isothermal or adiabatic (γ=5/3)(\gamma = 5/3). (b) State your final classification of the process.
