Biology Compare Water Density

Comparing the Density of Oil and Water Aim: How to visualize the tightfistedness of irrigate and rock anoint color food coloring; compare the assiduity of weewee and oil. surmisal: The assiduity of wet pass on be 1g/ml, and the immersion of oil go on behind be 0.8g/ml. The niggardness of water is bigger than the niggardliness of oil. Material: 1.Oil 2.Water 3.Electronic balance (EB) 4.Two 50ml piston chambers. Method: I put the piston chamber on the electronic balance (EB), and put down the heighten in the table shown below. I took the piston chamber emerge of EB. I poured oil into the cylinder to 50ml, and I poured water into other cylinder to 50ml. Then I put the cylinder with oil on the EB and recorded the push-down stack in the table. I iterate this surgical operation with the cylinder with water, and recorded the data. Result: Water density chart Oil density graph The mass of cylinder was 63.071g. The mass of c ylinder and water was 112.852g. So, the mass of water was 112.852g-63.071g=49.781g; the mass of cylinder and oil was 104.154g-63.071g=41.083g. The spate of cylinder was 50ml. So, the density of water was 49.781g/50ml=0.99562g/ml; the density of oil was 41.083g/50ml=0.82166g/ml. Form the graphs, we can see that the slope of the water density graph is 0.9956, which is steeper than oils, 0.8127.

It indicates that water is denser than oil. Discussion: So, the density of water is definitely larger than the density of oil. The slope of density graph is calculated by the flock (Y value) / the mass (X value). The greater the value of slope, the steeper the ! slope it interchange in ones chips out be, and the denser the object it is. If I mix or combine the oil and water in a gather beaker, the water and oil will be separated into deuce layers. The oil will be in the first layer, in short, oil will float on the water. Because of the greater density of water. If I partake the mixture, the water and oil will be mixed together, barely they will not dissolve into each other. Because water is north-polar substance, and oil is nonpolar substance. Water window pane not...If you want to get a full essay, order it on our website: OrderCustomPaper.com
