Question
Chapter 22, Problem 22.11E
Interpretation Introduction
Interpretation:
The change in pressure on coalscence of two
Concept introduction:
Surface tension is the tension of a liquid surface that causes due to the attraction of liquid particles in the liquid surface by the liquid particle present in the bulk of the liquid. The surface tension tries to attain a minimum surface area. The formula of surface tension is given by the expression as shown below.

The properties of two pure liquids, X and Y, are investigated. First, 50 uL each of X and Y were
added on a glass slide. It was observed that X formed globules while Y spreaded throughout
the slide. Furthermore, an instrument-based analysis showed that liquids X and Y have
comparable molar masses.
Based from the information above, which of these two:
1. Has a higher surface tension at a fixed temperature?
2. Is more likely to have hydrogen bonding interactions among its molecules?
3. Is more useful as a drying agent?
What is the correct order for the surface tension of the following substances?
Question 1 options:
C8H18 < CHCl3< H2O
H2O < CHCl3 < C8H18

CHCl3 < H2O < C8H18
Liquid A is known to have a lower surface tension and lower vapor pressure than Liquid B.
Use these facts to predict the result of each experiment in the table below, if you can.
experiment
Identical wire loops are dipped into Liquid A
and Liquid B, so that a film of liquid forms
across the loops (like the bubble solution on a
child's bubble blowing wand). The width of
each loop is increased slowly and the forces
F and F needed to make the loops 5%
wider are measured.
Small amounts of Liquid A and Liquid B are
sprayed into the air, where they form perfect
spheres with a volume of 45.0 μL. The
diameters of these drops are measured with
a high-speed camera, and their surface areas
SA and Sg calculated.
