Question

Which of the following suits best for two or more substances that are evenly distributed?

• A. Saline solution
• B. Muddy water
• C. Garden mud
• D. Copper wire

Answer 1

The correct option is A Saline solution

In muddy water, the mud settles to the bottom after some time. The mud is present in the bottom and the water will be present at the top. Thus, muddy water doesn't have a uniform distribution of substances.

Garden mud consists of several nutrients which may be concentrated towards the plant roots. Thus in garden mud, the substances are not uniformly distributed.

For better conduction of electricity, copper wire consist of only copper. Thus, copper wire doesn't consist of two or more substances which are evenly distributed.

Saline solution is a mixture of salt and water. The two substances, salt and water are evenly distributed to get a saline solution.
