The experiment is related to the demonstration using Pepper. When pepper is spread over water, it clumps together This is because pepper is hydrophobic. When repeated with sugar and salt, they instantly dissolved. This means they are attracted to water. When also sprinkled on the surface of the water, it floats. This is caused by surface tension.
To break the surface tension of water, one can use aeration or the use of chemicals such as soap molecules which contain a long chain of hydrogen as well as carbon atoms.
<h3>What is surface tension?</h3>
Surface tension is the propensity of liquid surfaces at rest to shrink to the smallest feasible surface area. Surface tension permits items with a higher density than water, such as razor blades and insects (such as water striders), to float on the water's surface without being immersed.
A force tensiometer can be used to measure surface tension. The forces exerted on a probe situated at the liquid-gas or liquid-liquid interface are measured by these devices.

Answer:65.4 meters= 65400 millimeters
Answer: The volume of the balloon up there is 6.192 L.
Explanation:
Given: 
= 1.80 L, 
= 785 mm Hg (mm Hg = 0.00131579) = 1.032 atm
= 0.300 atm, 
= ?
Formula used to calculate volume is as follows.
Substitute the value into above formula as follows.
Thus, we can conclude that the volume of the balloon up there is 6.192 L.
