Tested Vapor Pressure, Viscosity, And Surface Tensions

447 Words2 Pages

The experiment tested vapor pressure, viscosity, and surface tension. The vapor pressure was tested by putting a drop of the liquid on the laminated paper and waiting 30 second to see which one had reverberated. The viscosity was tested by putting a drops of different liquids on the laminated paper and holding the paper vertically to see which one fell the fastest. The surface tension was tested by how far the liquid spread when a drop of it was put on the laminated paper. The propanol had a high vapor pressure, a low viscosity, and a low surface tension. The high vapor pressure meant that when it was left it to evaporate it evaporated completely or the fastest. The low viscosity was seen when we raced the liquids and the propanol finished first. Lastly, the low surface tension was found when it spread the farthest. The reason for all of this is because proponal has a weak intermolecular force allowing the molecules to spread faster. …show more content…

The low vapor pressure is because it is was not completely evaporated like the propanal. The low viscosity is because it finished second behind the propanal when it slid down the paper. Lastly, the surface tension was low because it spread farther than the glycerin but not as far as the propanol. The intermolecular forces in water are stronger than propanol but still relatively weak. The glycerin had a low vapor pressure, a high viscosity, and a high surface tension. The high vapor pressure was found when it did not a evaporate at all. The low viscosity was shown since it was the slowest moving one by far. The surface tension was the highest because it did not spread the slightest bit. Glycerin has a strong intermolecular force because it has a low vapor pressure, a high viscosity, and a high surface

My experiment is elephant toothpaste were foam shoots out of a container or glass. I chose this experiment because I thought it would be fun to see foam shoot out of a bottle. You get to mix curtain substances together to make elephant toothpaste. I thought if I get a small bottle then the most foam should be produced.

Methanol Vapor Pressure Lab

Based on the obtained results from the experiment, the unknown liquid was determined to be methanol. The results were very close to the theoretical values, all within 15.92 % error. In this experiment it showed that the methanol have different intermolecular forces at work and at different vapor pressures implying that the amount of intermolecular forces they exhibit affects the vapor pressure. Possible source of error that occurred throughout the experiment was that the temperature was hard to control leading to the variances between the temperature of the reading in the water bath and the actual temperature causing slight changes in the vapor

Paper Towel Experiment

Be cautious when performing this experiment as water may spill on the floor, slip and injure yourself badly. Check the floor surface area for any puddles of water and wipe down with as many dry paper towels needed. Take care when handling with equipment that is made out of plastic or glass because when dropped, the glass or plastic may shatter into pieces which can be very dangerous. If needed, ask a responsible adult to help out in the experiment to avoid injuries.

Hydrogen Bonds Formed By Water Molecules Lab Report

Observing more evaporation in liquid A as compared to B suggest that the bonds in liquid A are less strong than those of B because the ability to move fast is promoted by when the bonds between a substance are less compact i.e. a gas intermolecular bonds are less strong that the intermolecular bonds that make up a liquid. c) Can cold water

In this experiment the scientist will be testing different liquids to see if all liquids evaporate at the same rate. The scientist will have water, orange juice, nail polish remover, Coke, a small cooking pot, and a stove. The scientist will boil all of the liquids and measure which liquids evaporated the fastest. The science behind evaporation is when all of the molecules are rapidly in motion. Liquids evaporate due to heat, which makes the molecules in a liquid to move faster.

Propylene Glycol Research Paper

529 Words | 3 Pages

Propylene Glycol Propylene Glycol is found in antifreeze, it is a humectant which means it is hydrating but is also a skin irritant. It is widely found in skin care products such as body washes, deodorants, shampoo, conditioner and liquid for e-cigarettes. This is because it is cheaper for companies to add this to their products rather than using botanical ingredients. By adding Propylene Glycol it prevents the product from spoiling in hot and cold temperature and helps products to sink into the skin. Although Propylene Glycolic can work into the blood stream.

Firstly, measure the refractive index of water five times and then measure for each of the pure liquids (toluene and cyclohexane). After that prepare 9 mixtures of toluene and cyclohexane carrying their volume fractions from 10 to 90 percent in increments of 10 percent using 10.0 mL volumetric flasks. The last step is to read the temperature in the thermometer. Then, determine the the boiling point for toluene and for cyclohexane. Finally, complete the part C: for this part, the composition of vapor and liquid phases of toluene-cyclohexane mixtures.

Boiling Point In Intermolecular Science

1053 Words | 5 Pages

(2005) states that all molecules have different boiling points, this is due to the intermolecular forces between the atoms. Therefore, the more intense the intermolecular force is the higher the boiling point, and the lower intensity, the lower the boiling point. This paper aims to discusses the order of the boiling points of 3-methyl-1-butanol and 3-methylbutanal, 1-Hexanol and 1-Pentanol, examining the differences between them. (De Marco et al. 2014).

Determining The Factors That Affect Evaporation Rates

1149 Words | 5 Pages

However, if the intermolecular force is in a medium range, it can be called dipole-dipole, which means that a permanent charge exits at opposite ends of the molecule and a stronger bond is formed. The purpose of this lab was to determine the factors that affect evaporations rates using multiple different liquids. By measuring the evaporation rates using a LabQuest and probe, it is possible to determine what kind of intermolecular force the liquid has, as well as what factors dictate the strength of the bond, because the faster a liquid evaporates, the weaker the intermolecular forces are due to them breaking apart rather easily to become a gas. The same goes but for the opposite; if a liquid takes longer to evaporate, it has a stronger intermolecular force and thereby the bonds between the molecules hold the substance more tightly together instead of breaking apart to

How Does The Concentration Of Substances To Water Change Its Surface Tension?

669 Words | 3 Pages

Main goal of the experiment The main goal of experiment is to determine, how adding different substances to water changes its surface tension, and how the concentration of those solutions influences surface tension. We would also like to examine, which of the chosen experimental method is more precise, reliable and efficient. Theoretical background of the experiment Surface tension is a physical phenomenon existing on contacting surface of liquid with gas, solid or other liquid, causing that the surface acts as elastic membrane. It may be also described as property of surface of liquid enabling it to resist an external force.

Physical Properties To Determine The Individuality Of An Unknown Substance

786 Words | 4 Pages

Hydrogen bonds: Hydrogen bonding is the strongest of the intermolecular bonds of them all. These are also a kind of permanent dipole forces and they are only found if hydrogen is present in the molecules. Molecules with stronger intermolecular forces have higher boiling and melting points. The molecules in a liquid slide past each other yet they are still closer to each other due to their intermolecular forces. A rise in temperature gives the molecules kinetic energy enough for them to break away from each other.

The first experiment demonstrated that when a cracker is placed in an environment with high relative humidity (e.g. 75%) at 25°C, it would absorb moisture from the environment until it reaches equilibrium. The moisture absorbs into the cracker due to its low water activity. The crackers would become soft as moisture is absorbed.
