Archimedes Principle Lab Essay

Topics: DensityPhysics

The spring constant of the spring was multiplied by the displacement, and then divided by gravity. I Volume of Lead gel . 0 g/ coxcomb=9. Xx-4 gate volume of the rod was found by dividing the mass of the zinc rob and the density of the fluid (water). I Density of density of the unknown squid was found by dividing the mass of zinc rob by the volume of the zinc rod. I Discussion: The objective of this experiment was to measure the density of a solid and an unknown liquid by using one of the oldest principles, Archimedes’ principle.

For part A of the experiment, we were able to use the spring constant found from the previous lab, in order to help determine the change in mass and volume of an object, and the density of an unknown liquid. The spring constant that was found from the previous lab was 0. 023 N/m. In part B of the experiment, we were able to determine the change in mass of he lead rod from the air to the water and the volume of the lead rod.

After conducting five trials, we were able to find the change in mass of the lead rod by using the spring constant formula of F=xx.

After modifying the formula to solve for mass, we were able to find the change in mass for each trial by multiplying the spring constant and displacement of the lead rod in air versus water, then dividing by gravity. The average change in mass was found to be 9.

XIII-g. Once we had found the mass of the lead rod, we were able to find calculate the volume of the lead rod by modifying the buoyancy force formula to solve for the illume of the object. Find that formula, we divided the mass of the lead rod by the density of water as shown in the table of literature. The average volume of the lead rod was found to be 3. 22 cam. In part C of this experiment, we were able to determine the change in mass of the lead rod from air to an unknown liquid and the density of the unknown liquid. We used the same method in part B to calculate the change in mass of the lead rod. The average change in mass of the lead rod in the unknown liquid was found to be Since the volume of an object does not change when submerged n various liquids, we were able to use the average volume of the lead rod found in part B. Then, we were able to find the density of the unknown liquid by dividing the mass of the lead rod by the volume of the lead rod.

Average density of the unknown liquid was found to be 1. 344 g/cam. Since the unknown liquid had an aroma of rubbing alcohol, we hypothesized that the unknown liquid was a mixture of rubbing alcohol and water. Using Archimedes principle, our hypothesis can be supported since the average density of the unknown liquid was 0843 g/ml. An alternative method for this experiment would be to set up he beaker so that the liquid level would be completely leveled, versus when a person lifts the beaker with an unleavened liquid level.

Away a person could do this would be to place a book under the beaker with a leveled liquid level, so that the lead rod is equally and fully submerged in the liquid. Conclusion: The objective of this experiment was to determine the mass and volume of an object and the density of an unknown liquid using Archimedes Principle. For part A, we used the spring constant from the previous lab to help determine the mass of the lead rod in part B. The displacement of the lead rod from the air to the eater was found in order to help determine the average mass of the lead rod.

The average change in mass of the lead rod from air to water was 9. Xx 0-g. The average volume of the lead rod was 9. Xx-CM. In part C an unknown liquid was used. A similar method was used to determine the average change in mass of the lead rod in the unknown liquid, which was found to be 7. Xx-g. Since the volume of an object does not change in different liquids, the volume of the object found in part B was used in part C to help determine the density of the unknown liquid. The density of the unknown liquid was 0. Egg/ml.
