The ratio of the final P, and initial P; pressures of a diatomic ideal gas undergoing adiabatic expansion is given by the equation: Pf Pi www Where V, is the initial volume and V, the final volume of the gas. A sample of H at conditions where it behaves as a diatomic ideal gas is subjected to an adiabatic expansion from the initial condition: Seleccione una Ola. V Sv = (1.0 0.1)m and P; 4p, = (100 5)kPa to a final volumen: Vf Svf = (2.00.1)m b 1.4 SPF Which of the following expressions is the correct one to calculate the relative standard deviation of the final pressure Pi Write your complete procedure. ?
