Logarithms of readings of pressure and volume for an ideal gas were plotted on a graph as shown in Fig. By measuring the gradient, it can be shwon that the gas may be A. monatomic and undergoing an adiabatic changeB. monatomic and undergoing an isothermal changeC. diatomic and undergoing an adiabatic changeD. triatomic and undergoing an isothermal change |

Answer» Correct Answer - C c. `log P = m log V + C_(1)`, where `C_(1)` is positive, `m` is slope `m = (2.38 - 2.10)/(1.1 - 1.3) = 1.4` `log P = 1.4 log V + C_(1)` `log PV^(1.4) = C_(1)` `PV^(1.4) = k` Thus, it represent an ideal diatomic gas undergoing adiabatic change. |
