Viscosity Science Lab Essay Example for Free

Viscosity Science Lab EssayPurposeTo determine of changing the viscousness will affect the time it takes for a marble to flow through a liquid.HypothesisIf a marble is dropped into suffice flog and lemon yellow syrup, than I predict that the marble in the traveling bag soap will travel faster than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than then the viscosity of the deal soap. Also, the particles in the corn syrup are more compact than those in the dish soap. This makes the marble sink faster in the dish soap than the corn syrup.Apparatus* 2 identical marbles* 250 Graduated Cylinders of 250mL* 250mL of dish soap* 250mL of corn syrup* 1 timer/stopwatchProcedure1. force out one marble in the graduated cylinder of corn syrup and begin timing2. Continue timing until the marble hits to the bottom and stop the timer3. Record the time result in the qualitative chart4. Record all observations in the quantitative chart5. Repeat all steps from 1-4 fir tree the graduated cylinder of the dish soap6.

I discovered that a marble travels approximately 7 seconds in 250mL of dish soap and approximately 87 seconds in corn syrup. Also, I found that the corn syrup is more viscous than the dish soap which is what caused the slow and fast sinking. This result occurred because the particles in the corn syrup are much larger than mean(prenominal) particles. These large particles within the corn syrup take up more space. Since the particles take up so much space, they tend to block from each one otherwise and non le t them pass through. It is very difficult for large particles to move past each other unlike humbled, tiny particles, like those in the dish soap.The particles in the dish soap are very small and set up move more freely and quickly. In the dish soap, the particles are very small and can move past each other easily when compared to the particles in the corn syrup. Another reason also contributed to the result of this experiment. Attraction. Some types of particles tend to draw off more than others and that is exactly what happened in the corn syrup.The particles in the corn syrup attracted more than the dish soap. The large particles in the corn syrup held tightly to each other, that when the marble fell in that it made it hard for the marble to pass through more than one particle at a time. IN the dish soap, the particles did not attract as much as the corn syrup which let the marble move easily and quickly through the liquid. The strength of leader as well as the particle size is important in determining a fluids viscosity.ApplicationThis viscosity experiment can be used in real-life when making sun-tan lotion as well as other cosmetic products. It is important for the lotion to be viscous because the lotion could not be applied and spread around thebody if the cream was not viscous enough to suit its use. It would drip all over you It wouldnt dry or stay in one place. Many well-known business organizationes hire highly educated scientists to calculate the right viscosity level and if it is not correct nobody would buy the product.People who once thought highly of the product would think that it has gone bad and useless. Profits would go down for the business and since nobody would by it, the business would have to be shut down. Many jobs would be lost and many businesses would have to be shut down. Jobs from the factory, the transport services, the marketers, and the sell stores would be lost and many people left with nothing but a pension. Viscosity is seen all around the world and it is very important for the measure of viscosity to be pin-point and accurate.
