1 Density and Archimedes Principle 11-cor Objectives: To understand the concept of density and its relationship to various materials. To understand and use Archimedes Principle. Equipment: Dial calipers, Graduated cylinders, Solid aluminum, brass, steel cubes, cup size water containers, variety of irregular shapes, Electronic scales (200 g, 1 g resolution), 1- Electronic scale (2000 g, 1 g resolution), 2 lbs table salt, sugar Must be in a room with a sink. Background: Density ( ) is defined to be the mass of a material contained in a unit volume of the material: = m/v, where m is the total mass of the object and V is its volume. The usual units are g/cm 3 or kg/m 3. The importance of density is that for different objects made of the same material the mass and volume will vary from object to object but the density remains the same it only depends on the material used. Table 1 gives the density of some common materials. Table 1 - Density of Various Materials material (g/cm 3 ) material (g/cm 3 ) material (g/cm 3 ) aluminum 2.70 gold 19.3 platinum 21.4 brass 8.56 iron 7.86 water 1.00 copper 8.93 lead 11.3 zinc 6.92 One of the activities described in Part II, is to study how the density of water changes as you dissolve a material in it. Salt is highly ionic and dissociates into Na + and Cl - ions. Sugar, on the other hand, does not dissociate when it dissolves. Measuring the changes in volume gives you information about the nature of how the salt ions and sugar dissolve in water. Archimedes Principle states that a body, immersed in a fluid, feels a buoyant force such that: if the body sinks, the buoyant force is just equal to the volume of the body times the density of the fluid. Once the object lies on the bottom of the container, three forces act on it: the buoyant force B, the normal force N (NOT YET DRAWN), and the weight of the submerged object mg. These three forces of course cancel each other because the object stays at rest at the bottom. Density -- 1
2 g V mg if the body floats, the buoyant force equals the volume of displaced fluid times the density of the fluid times g. In this case only two forces act on the floating body: the buoyant force and its weight. Therefore the buoyant force alone must cancel the weight m g. B = mg = g V* V* = volume of water displaced mg Note that in both cases the buoyant force equals the weight of the displaced fluid. PART I Activity 1. There are rectangular blocks made of several different materials available. Measure the dimensions and mass of three different metal blocks and calculate their densities. Identify the material and compare with your calculated density. To measure the dimensions of the shapes, you will need to use a dial caliper. Handle the caliper with care. Note the units used on the caliper. Activity 2. Determine the density of a cube of metal (aluminum or brass or steel). Weigh the metal on the electronic scale. Also weigh it using the computer interfaced force probe. Put a beaker of water on the electronic scale and record the weight. Suspend (with steady hands, elbows resting on the table) the unknown metal from the force probe and slowly lower it into the water. Record the changes in the scale and the changes in the force probe readings for several depths of immersion and when it is completely immersed. Explain why the readings change as they do. (Note that water exerts a buoyant force on the metal cube. Therefore by Newton's third law, the cube exerts a force Density -- 2
3 on the water in the opposite direction.) Using your data for complete immersion, calculate the density of the metal. Compare with the value given in Table 1. NOTE: For using the computer interfaced force probe, do the following. 1. Be sure that the probe is connected to Port 1 of the computer interface. 2. Open Archimedes.xmbl file in the physics 161 course folder. Skip next point 3; only do point 3 if absolutely necessary, i.e. if for zero force the force probe reading is not close to zero!! 3. Click "Experiment" menu and select "zero". This procedure sets the "zero" of the scale of the force probe. 4. The Logger Pro program is set to measure the force for 5 minutes. This time interval can be shorter if desired. If you do Analysis Statistics of a constant force measurement over a short time, you can improve the accuracy of your force reading. Aim for three significant figures. Activity 3. Now repeat the experiment similar to what Archimedes did. Determine the density of 2 pieces of irregular shaped unknown metals (ring, slab, sphere, trapezoid, kings crown). Do this by measuring the weight of the object, then again measuring the weight after complete immersion in water. The second measurement allows to determine the buoyant force. Since the buoyant force equals the weight of the displaced water, this allows for finding the density of the object compared to the density of water. So is your object made of pure gold like in Archimedes assignment? Finally, determine the density of an irregular object that will float in water. Use your imagination and any available scales. PART II Activity 4. Investigate how the density of water changes when you dissolve salt in the water. Fill a graduated cylinder with about 200 cc of water and carefully measure the volume. Weigh out g of salt (sodium chloride, density 2.16 g/cm 3 ), add it to the water, and measure the new volume. Make sure all salt has dissolved!! What can you conclude from the volume measurement about the sizes of Na and Cl ions? Activity 5. Repeat Activity 4 for sugar (sucrose C 12 H 22 O 11, density 1.58 g/cm 3 ). [As an aside, note that a typical 240 cc soft drink contains ~30 g of sugar.] Compare the results with activity 4. Density -- 3
4 Density and Archimedes Principle (preliminary questions) Name: Section: Date: 1. A beaker, filled to the very top with water, weighs 15 N. A 300 g weight is carefully dropped into the beaker. The water that overflows is wiped away and the beaker is weighed again. It weighs now 16.9 N. What is the density of the weight? Hint: The force on the bottom of the beaker equals (the weight of the reduced volume of water + the 300 g weight). 2. The beaker is refilled to the top with water and a 100 g piece of wood of density 0.8 that of water is carefully floated on the water. What volume of water overflows? 3a. NOTE: The claim is that melting of Arctic sea-ice, including large icebergs, does NOT increase sea-level, but that melting of Greenland or Antarctic glaciers does increase sea-level. 3b. Why are both claims made in 3a. correct? Density -- 4

6 Activity 2. Density of metal cube. (by method of Archimedes, do NOT use results of Activity 1.) Cube: Weight with force probe: (N). Does this agree with the cube placed on the scale? (kg) Beaker-water: Weight on scale: (N). Yes/No NOTE: Scale registers mass (kg). Convert this to a force (N). Record both numbers Depth of immersion Zero 1/4 1/2 3/4 4/4 fully immersed, but still suspended Scale (N), see NOTE above Force probe (N) Scale + probe (N) Buoyancy (N) Re-check the readings for zero immersion. If they are not the same, you spilled water, and you have to repeat all measurements. Draw all forces acting on the metal cube at complete immersion. How many forces act on the cube? Which of these forces were measured in above table? Draw all forces acting on the beaker-water system for complete immersion of the cube. How many forces act on the system of beaker-water? Which of these forces were measured in your experiment? Density -- 6
7 Explain why the scale reading, the force probe reading, and the sum of both readings change as they do, as you vary the depth of immersion. Why should the sum remain constant?. From the data in the table: Calculate the buoyant force for each immersion of the cube and complete the fifth column in the Table with the results. (3 significant figures) (Do NOT use the results from Activity 1.) Using your numbers, calculate the density of metal in the cube. Show your work. Activity 3. For 2 different non-cubic metal shapes find the density of each metal using the method of complete immersion in water.
