Rocks are intriguing to many individuals all over the world. Being made up of one or even many minerals, rocks draw an overwhelming amount of attention to themselves. When a probe brought back samples of rock from Planet X the task of identifying the rock was assigned. With no prior knowledge of the type of rock presented one will need figure out the identity of the rock based only on its density and physical properties. With an experimental process, one will begin to compare and uncover the identity of the rock samples brought back. To begin with, is the experimental process used to determine the identity of the rock. In doing so one will need to discover the density of the rock. By measuring the rock sample with grams per milliliter is a way used to figure out the density. In starting one will need to measure the mass of the rock using grams. Then using a set milliliter amount of a liquid substance, such as water, one will place the rock sample inside. By reading the new volume of the liquid substance amount one will then subtract the initial milliliter amount from the final volume reading, thus giving you the volume of the rock sample. Using the mass of the sample rock obtained one will then divide the final volume reading unveiling the density of the …show more content…

With the discovery of the rocks density, as shown in Document B, as being 2.64 grams one can now compare it to other rocks. In comparing the sample rock to common rocks the density is very similar and close to many of the common rocks in the chart given in Document A. The density of the rock found on Planet X can vary in impure varieties as stated in Document B. Physical properties of the sample rock are color, which is clear in its pure form, the melting point of one thousand six hundred and forty eight degrees celsius, and that is it not soluble to water, all of which are presented in Document
