Question

Discard the water from the first step and re-fill the tall drinking water glass with the chilled water. Then slowly pour a small amount of the hot, green freshwater into the water in the drinking glass. Describe and explain you observations.

Answer 1

The hot water remains at the top of chilled water.

Step-by-step explanation:

The hot water remains at the top of chilled water because hot water has less denser as compared to chilled water. Due to higher density of chilled water, it remains at the bottom due to its greater mass while on the other hand, the hot freshwater goes upward and spreads at the top of the chilled water due to lower mass so when the hot water is added to the chilled water, hot water remains at the top.
