Question

A.Milk
B.Butter
C.Jelly
D.All of the above

Answer 1

A mixture is referred to as the physical association of two or more substances, when mixed they do not lose their identity because there is no chemical reaction involved between the substances or its constituents.

Complete step by step answer:
In order to classify as mixture, it should have certain properties such as:
consists of two or more kind of compound or elements which are associated physically,
By physical means it can be separated into its components,
On combining with each other it often retains its components.

Types of mixture:

Mixture formed can be heterogeneous or homogeneous in nature:
First we will study about heterogeneous mixture;
Word hetero means, different so, heterogeneous mixture are the result when elements with
different composition and properties are mixed. Example: sugar mixed in salt, combination
of water and oil.
Homogenous mixture;
The mixture formed is a homogeneous mixture. Example: sugar or salt solution.
When sugar or salt is mixed with water, it gets mixed uniformly, we cannot find sugar or salt in water.
If we talk about milk, so milk is a mixture or emulsion formed of soluble fat globules in water.
Butter: It is a homogeneous mixture formed of water and soluble fat.
Jelly: It is a heterogeneous mixture formed of colours, flavours and sugar.

Thus, the correct option is A since it is used as food supplement.

Note:
When mixture is formed, its properties are the result of its constituent’s properties. The state of mixture can be solid, liquid or even gas. And in the process of formation of mixture, we see that there is no change in the internal energy of the system.
