Sieving, Vaporization, Solution, Purified Water

Explanation:

1) Separating out gram from mixture of gram and wheat can be done by sieving.

A sieve is a device that has a mesh and the hole size helps us to separate mixed grains depending on the size difference.  

2) Conversion of liquid into vapours is called Vaporization.

Vaporization is the process in which a liquid changes into vapour when heated.

3) Soft drink is an example of solution.

A solution is a homogeneous mixture of particles that do not settle down at the bottom of the container. The particles are very small that they cannot be seen with a microscope.

4) Purified Water is used in making medicines.
