Text Solution

Verified by Experts

(1) A system is said to be homogeneous if phase `(P)=1` . A system with `P ge 2` is heterogeneous.
(2) To determine phase follow the rules given below.

`{:("Given system",a,b,c,d,e,f,g),("Number of phase",2,2,2,2,1,2,3):}`
Homogeneous system are: e,
Heter ogenous system are: `a, b, c,d, f, g`
