Fluid Density - r5 - hjective: To develop a theory about how weight-"mass, volume and type of material affect density- Introduction: Scales usually measure one of two things: mass or weight. I'm-{ass is the amount of matter, andweight is the reaction of amass to gravity. l'v'Iass is usually stable, changing only if material is added or subtracted. Weight, however= depends on which forces are acting on the mass. Weight varies with height, to the point where objects can be weightless! Also, other forces besides gravity can aect a measurement meant to indicate an object's weight. The purpose of this experiment is to understand the meaning and signicance of the density of a substance and buoyant force. Density is a basic physical property of a homogeneous substance; it is an intensive property, which means it depends only on the substance's composition and does not vary with size or amount. The determination of density is a nondestructive physical process for distinguishing one substance from another. Density = mass!r volume Archimedes Principle The buoyant force, F3 on an ohiect is equal to the weight of the uid it displaces when it is submerged in the uid. Here buoyant force FB = density X volume 2; gravity 'When there is no overow, buoyant force FE is found om difference between weight in air and weight while submerged in liquid. Apparatus: This lab will be completed using online simulation. Use the following linkto access the simulation. [fyou do not have Flash Player installed, it might not run. Rerun the simulation aer you install Flash player. Force Buoyant vs. Acceleration due to gravity Click on 'Begini Click on 'Fluid' until it changes to 'Gasoline'. . Cn open program, select: Earth, 'Bottle 1Volume of SmL' and Mass of 1,000\" grams. . Click on 'Start' and allow enough time for bottle to be completely submerged and motionless. Graph shows total time as sixteen seconds. . Obtain from your graph values for force in air and force when submerged in uid. Subtract these forces to get buoyant force. . Click on location: to change. Repeat procedure for all other locations available in this simulation. Leave all other parameters unchanged except location Record data in table below. .

Click 'Reset' on the lower right of simulation screen. Select fluid as 'Gasoline'. B. Select location as 'Earth', Bottle Volume as 100mL, mass as 2,000 grams. C. Start first trial and allow 16 seconds to elapse before you read values off graph. As in previous run, subtract reading of force when in fluid from force when in air to determine buoyant force. D. Click on 'Fluid' to change fluid. Do not change any other parameter. Now repeat experiment for all available fluids in simulation. (e) Record data in table below E.

Click 'Start' and allow 16 seconds to elapse before you read values off graph. As in previous runs, subtract reading of force when in fluid from force when in air to determine buoyant force. D. Click on 'Bottle Volume' to change volume of bottle. Do not change any other parameter. Now repeat experiment for seven different 'Bottle Volumes' available in simulation. E. Create a data table and record your experimental data. F. Plot a graph of Force Buoyant Vs Volume.Discussion 1. How did the location (different gravity) affect the forces in air, fluid, and buoyancy? 2. How did the type of fluid affect the forces in air, fluid, and buoyancy? 3. Describe the relationship of Force Buoyant and Bottle volume based on your plot you made in #3. 4. How does adequate experimentation help you make accurate prediction
