Viscosity Science Lab Essay Example for Free

cloyingness Science Lab EssayPurposeTo determine of changing the viscosity will affect the period it takes for a marble to flow through a liquid.HypothesisIf a marble is dropped into traveling bag goop and maize sirup, than I predict that the marble in the dish soap will travel hot than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than thusly the viscosity of the dish soap. Also, the particles in the corn syrup ar overmuch compact than those in the dish soap. This makes the marble sink faster in the dish soap than the corn syrup.Apparatus* 2 alike marbles* 250 Graduated Cylinders of 250mL* 250mL of dish soap* 250mL of corn syrup* 1 timer/stopwatch cognitive process1. Drop one marble in the graduated cylinder of corn syrup and begin clock2. 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 al l stairs from 1-4 fir the graduated cylinder of the dish soap6.

I discovered that a marble travels most 7 seconds in 250mL of dish soap and approximately 87 seconds in corn syrup. Also, I fix that the corn syrup is more sticky 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 normal particles. These large particles within the corn syrup take up more space. Since the particles take up so much space, they tend to block individually other and not let them pass through. It is very(prenom inal) difficult for large particles to move past for each one other unlike small, tiny particles, like those in the dish soap.The particles in the dish soap are very small and can 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(prenominal) reason also contributed to the result of this experiment. Attraction. Some types of particles tend to attract 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 military capability of attraction 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 businesses hire highly educated scientists to calculate the right viscosity aim and if it is not correct nobody would buy the product.People who once thought highly of the product would trust that it has gone bad and useless. Profits would go down for the business and since nobody would by it, the business would take hold to be shut down. Many jobs would be lost and many businesses would have to be shut down. Jobs from the factory, the transportation services, the marketers, and the retail stores would be lost and many people left with nothing but a pension. viscousnes s is seen all around the world and it is very important for the measurement of viscosity to be pin-point and accurate.
