Problem

An ideal mono-atomic gas (take γ=5/3\gamma = 5/3) initially at P1=3.0×105 PaP_1 = 3.0 \times 10^{5}\,\text{Pa}, V1=0.015 m3V_1 = 0.015\,\text{m}^3, and T1=300 KT_1 = 300\,\text{K} is taken to a new state with P2=1.2×105 PaP_2 = 1.2 \times 10^{5}\,\text{Pa} and V2=0.030 m3V_2 = 0.030\,\text{m}^3. The work done by the gas during the change is measured to be 2.5\,kJ. Which statement correctly classifies this process? (a) It is adiabatic (b) It is isothermal (c) It is neither isothermal nor adiabatic (d) It is isobaric
