The pressure and density of a diatomic gas
WebbThe pressure and density of a diatomic gas ( gamma = 75 ) change adiabatically from (P1,ρ1) to (P2,ρ2) . If ρ2ρ1 = 32 , then P 2P 1 should be. Class 11. Webb8 mars 2024 · From the equation (1), we can state that the pressure of the gas is equal to two thirds of internal energy per unit volume or internal energy density. Writing pressure in terms of mean kinetic energy density. where ρ = nm = mass density (Note n is number density) Multiply and divide R.H. S of equation (2) by 2, we get.
