Drop each of the blocks into the water, one at a time. Based on the behaviour of the blocks, identify whether the blocks have a density greater than, equal to, or less than the density of water. Circle your answers below. /6 . 6 f, 4 (H 1A: greater than, equal to, less than: density of water 13: greater than, equal to, less than: density of water 1C: greater than, equal to, less than: density of water / 1D: greater than, equal to, less than: density of water Z 9 6 1E: greater than, equal to, less than: density of water 3. Measure the mass of each of the blocks. Then, one at a time, drop the block into the water. Hold any blocks that tend to float under the water. Record the level that the water rises to with the 2 59' \"I block fully submerged. From this, determine the volume of the block. Enter this data into the o M N {4'1\" table below. Make sure that you record the mass of the block and volume of the block to correct 9/}(5 significant figures.

Calculate the density of each block in kgfL (w! correct sig. figs). Then, perform a unit conversion to express the density of the block in kg,,'m3 [w/f correct sig. figs). Express your density in kg/m3 in scientific notation so that significant zeros are clearly identified. Show a sample calculation of your work below. fl- 5. Suppose you are told that Block 13 and Block 1E are two different samples of the same material, but with different degrees of impurities which means that their density yalues ought to be similar, yet different. Compare their values using a percentage difference calculation and show / your work below. ) 6. You are told that block 1A is supposed to be made out of diamond. Use the app to find the reference density of diamond and compare your experimental value to the accepted value using / a percentage error calculation. I Physics 104 Lab Manual Camosun College 2020 /
