Answer
(1) The properties of homogeneous system are uniform throughout the phase or system.
(2) The homogeneous systems are :
- Solutions of miscible liquids (water and alcohol) or soluble solids in liquids, ( $NaCl$ in water), etc.
- Mixture of gases. $H _2$ and $N _2, NH _3$ and $H _2$, etc.
(2) Heterogeneous system : A system consisting of two or more phases separated by interfacial boundaries is called a heterogeneous system.
Explanation : These systems are :
- Mixture of two or more immiscible liquids. E.g. Water and benzene.
- Solid in equilibrium with liquid.
E.g. Ice $\rightleftharpoons$ water.
- Liquid in equilibrium with vapour.
E.g. Water $\rightleftharpoons$ vapour.
