Doing laboratory work, you measured body weight, comparing rh scales weight weights weighing. At equilibrium balance these masses are equal. Imbalance means that the mass of bodies is not the same. Weight iron cylinder mass of aluminum. But the volume of the cylinder level. Hence, unit volume rh scales (1 cm3 or m3 1) gland has more weight than aluminum.
Mass of substance contained in unit volume is called rh scales density of matter. To find the density, it is necessary to divide the mass of the substance to its volume. Density affects the Greek letter? (Ro). then
By comparing the density of iron? As = 7800 kg / m3 and aluminum? Al = 2700 kg / m3, we understand why the experiment (see. Fig. 122) the mass of the iron cylinder was more weight aluminum cylinder of the same size.
Formula density of matter? = M / V is applied to homogeneous bodies, v. E. For bodies rh scales that consist of a single substance. This body, with no air pockets or not containing impurities other substances. According to the measured rh scales density value is judged on the purity of the substance. Do Not added, such as gold ingot into any cheap metal.
It would have changed the balance of the scales (see. Fig. 122) had iron cylinder instead of a cup placed rh scales a wooden cylinder of the same volume? What is density? Does the density of matter from its scope? From the masses? In what units is measured density? To go from one density g / cm3 density per unit kg / m3? I wonder!
Typically, a substance in the solid state has a density greater than the liquid. The exception to this rule is ice and water molecules consisting of H2O. The density of ice? = 900 kg / m3, the density of water? = 1000 kg / m3. The density less than the density of water ice, indicating rh scales less dense packing of molecules (v. E. Large distance between them) in the solid state of matter (ice) than in the liquid (water). In the future, you will meet with other very interesting abnormalities (abnormal) rh scales in the properties of water.
The average density of the Earth is about 5.5 g / cm3. This and other facts known to science led to some conclusions about the structure of the Earth. The average thickness of the crust about 33 km. The crust is composed primarily of soil and rocks. The average rh scales crustal density is 2.7 g / cm3, and the density of rocks that lie directly beneath the crust - 3.3 g / cm3. But both of these values are less than 5.5 g / cm3, v. E. Less than the average density of the Earth. It follows that the density of matter that is in the depths of the world, more than the average density of the Earth. rh scales Scientists suggest that the center of the Earth matter density reaches a value of 11.5 g / cm3, v. E. approaching the density of lead.
Low density wood (2 times less than cork) is balsa wood. Because it makes rafts, life belts. In Cuba, the tree grows eshinomena kolyuchevolosaya, rh scales wood has a density which is 25 times less than the density of water, v. E.? = 0.04 g / cm3. Very high density wood snake in the tree. Tree sinks in water like a stone.
Measure the density of soap. To do this, use a bar of soap rectangular shape. Compare the value of the measured density values you obtained your classmates. Is the level of the values of density? Why?
Already during the life of the famous Greek scientist rh scales Archimedes (Fig. 124) about it a legend, which served as a pretext for his invention, which impressed his contemporaries. One legend says that the king of Syracuse Heron II asked thinker identify with pure gold or made its crown jeweler or pidmishav there a significant amount of money. Of course, while the crown was to remain intact. Determine the weight of the crown Archimedes was not difficult. Much more difficult to accurately measure the volume of the crown to calculate the density of the metal from which it is cast, and determine whether it is pure gold. The difficulty was that she had an irregular shape!
