Question

You have two containers. One with pure 1000ml milk and another one which has 900ml of milk with 100ml water mixed in it. Which properties of liquid would you use to find out which container has pure milk.?​

Answer 1

Answer:

Let the initial quantity of milk =10xlitres,  

For each 1 litre, 200 ml of water is added, so after adding water, quantity of mixture become =12x litres.  

Now 6litres  of mixture is sold, and 10 litres of milk is added.  

So remaining quantity is (12x−6+10)=(12x+4)

In this final quantity, milk =10x

initial quantit is 20l

Answer 2

Viscosity

Explanation:

Viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids corresponds to the informal concept of thickness . Every liquid have some particular viscosity values. The unit of viscosity is poise

The viscosity of the water is approximately 0.01 poise.

The viscosity of the milk is 1.5-2.0 centipoise.

Based on this viscosity (the opposition to flow or the thickness) we can easily decide that which container have the pure milk.
