If the pure water in the left arm of the u-tube is replaced by a solution more concentrated than the one in the right arm, what will happen?

Water will move from left side to right side in the U-tube

Explanation:

Osmosis refers to the movement of the solvent molecule (water) from a low concentration of the solute to high concentration of the solute or from a high concentration of water to the low concentration of water.

The experiment was performed to demonstrate the osmosis using a permeable membrane which allows the movement of the solvent particles and U-tube.

When the left side of U-tube contained pure water and the right side contained concentrated solution with a high amount of the solute and low amount of water then the water will move from the higher concentration to lower concentration or from left side to right side.

Thus, Water will move from left side to right side in the U-tube.

To answer this question, we need to understand the concept of "specific heat" for water with respect to other compounds. According to the definition, specific heat of any substance is the amount of heat required to raise the temperature of that substance (per unit mass) by one degree Celsius (Q = c.m.ΔT).

It has been scientifically proven that the specific heat of water is higher than any other substance. This means that if the water is present in any environment, it will have the capacity to absorb more heat as compared to the area where no water is present. Further, water absorb heat during hot climate and then releases back during cold climate. This is the reason that, in Florida, where water is present, fluctuation in the temperature are only 5 degrees Celsius. On the other hand, in the desert, no water is present and thus fluctuations in temperature are high and can be directly linked to the presence and absence of sunlight during day and night along with other environmental parameters.
