Question

What two properties show that the drink is a fluid

Answer 1

Two properties that show that the drink is a fluid/liquid include its retention of volume and its conformation to the shape of its container. 

Answer 2

Step-by-step explanation:

Fluids have certain characteristics. Two of them are:

1. They do not resist any permanent deformation. In other words they can't resist shear (unaligned) forces applied on them.

2. They have ability to flow because of which they can take shape of the vessel they are kept in.

The drink also have these characteristics thus we can call that fluid.
