Question
Chapter 22, Problem 22.12E
Interpretation Introduction
Interpretation:
The approximate surface tension of a liquid required such that a razor blade will not float on is to be calculated.
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 minimum surface area. The formula of surface tension is given by the expression shown below.

- An amorphous solid can sometimes be converted to a crystalline solid by a process called annealing. Annealing consists of heating the substance to a temperature just below the melting point of the crystalline form and then cooling it slowly. Explain why this process helps produce a crystalline solid.arrow_forwardThe test tubes shown here contain equal amounts of the specified motor oils. Identical metal spheres were dropped at the same time into each of the tubes, and a brief moment later, the spheres had fallen to the heights indicated in the illustration.

Because chlorine is more electronegative than iodine, this molecule is a dipole.

Once the boiling points of each sample are reached, the samples are heated for an additional 4.60 min, which results in the vaporization of some of each sample. After 4.60 min, the samples are cooled and the masses of the remaining liquids are determined. The process is performed at constant pressure. The results are recorded in the table.

- please explainarrow_forwardCite some possible applications of determining the melting point of a substance. Explain briefly.arrow_forwardThe approximate molar mass of a volatile liquid can be determined by:1. Heating a sample of the liquid in a flask with a tiny hole at the top, which converts the liquid into gas that may escape through the hole2. Removing the flask from heat at the instant when the last bit of liquid becomes gas, at which time the flask will be filled with only gaseous sample at ambient pressure3. Sealing the flask and permitting the gaseous sample to condense to liquid, and then weighing the flask to determine the sample’s mass as shown.arrow_forward
