Which of the following is not a result of surface tension in water? a. water has an unusually low vapor pressure
b. drops tend to become spherical
c. surface area is maximized
d. surface appears to have a “skin”

The option which isn't a result of surface tension in water is: c. surface area is maximized.

Water can be defined as a liquid molecule that comprises the chemical element hydrogen and oxygen in the ratio of two to one (2:1).

Surface tension can be defined as a property of liquid such as water, which makes its surface to resist an external force due to the cohesive nature of its molecules.

This ultimately implies that, the surface tension of a liquid is mainly as a result of the cohesive forces existing between its molecules.

Generally, the surface tension of water is typically higher than the surface tension of most liquids.

Due to the effect of surface tension in water;

Additionally, the surface tension of a liquid such as water can be described as an inward force which tends to minimize its surface area rather than maximize its surface area.

In conclusion, surface tension in water doesn't maximize its surface area.

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
