How will a diffusion coefficient `D` and the viscosity coefficient `eta` of an ideal gas change it its volume increases `n` times : (a) isothermally , (b) isobarically ? |

Answer» `D alpha(sqrt(T))/(n) alpha V sqrt(T), eta alpha sqrt(T)` (a) `D` will increase `n` times `eta` will remain constant if `T` is constant (b) `D alpha (T^(3//2))/(p) alpha((p V)^(3//2))/(p) = p^(1//2) V^(3//2)` `eta alpha sqrt(p V)` Thus `D` will increase `n^(3//2)` times, `eta` will increase `n^(1//2)` times, if `p` is constant. |
