Report
Angel Le, Haadiyah Hanif, Elizabeth Gondek, Helena Pecci, Colin Lombardi Directions: Using the simulator, every group member will choose a different fluid (from the options provided in the Tables) to experiment with. Each member will select a different bottle volume such that the bottle can be completely submerged in the fluid. After adjusting the parameters, click "Start." Scroll down on the simulator to display the Force vs. time graph. Document the weight in air of the bottle (before submerging) and the apparent weight in the fluid (after submerging). From these measurements, calculate the buoyant force and record in Table 1. Table 1: Buoyant Force = Weight in Air - Weight in Fluid (Experimental) Fluid Fluid Density (kg/m 3 ) Bottle Volume (convert from mL to m 3 ) Weight in Air (N) Weight in Fluid (N) Buoyant Force (N) Fresh Water 1000 Gasoline 737 Maple Syrup 1333 Crude Oil 825 This difference in apparent weight (when the bottle is in air vs. when submerged in the fluid) will be the experimental buoyant force. For the theoretical buoyant force, use the equation for Archimedes' Principle in Table 2: Table 2: Buoyant Force = Weight of Fluid Displaced (Theoretical) Fluid Fluid Density (kg/m 3 ) Bottle Volume (m 3 ) Buoyant Force (N) Fresh Water 1000 Gasoline 737 Maple Syrup 1333 Crude Oil 825
Analysis: Table 3: Weight Method vs. Volume Method Fluid ΔW F B % Difference Fresh Water Gasoline Maple Syrup Crude Oil Question: Change the fluid to mercury and observe what happens with most bottle densities (any combination of bottle mass & volume). What does this say about the density of mercury?
