At the same conditions of pressure, volume and temperature, work done is maximum for which gas if all gases have equal masses?

Answer»

`NH_(3)`
`N_(2)`
`Cl_(2)`
`H_(2)S`

SOLUTION :When p,V and T are same and mass is also same, WORK done depends only UPON molecular mass.
`W prop (1)/(M)` (where M=molecular mass)
Among the given gases, `NH_(3)` has lowest molecular mass, so work done is MAXIMUM for it.
