A certain gas effuses out of two different vessels A and B.A has a circular orifice while B has a square orifice of length equal to the radius of the orifice of vessel A. The ratio of rate of diffusion of the gas from vessel A to that from vessel B is

Answer»

`pi:1`
`1:pi`
`1:1`
`3:2`

Solution :Under DIFFERENT CONDITIONS of pressure and temperature:
rate `alpha(PA)/SQRT(T M) "":. R_1/r_2 =P_1/P_2 A_1/A_2sqrt((T_2M_2)/(T_1M_1))`
