purpose of my project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the

Abstract Finding the melting point of an organic substance is a practical and efficient way for scientists to identify an unknown substance or determine a known substance’s level of purity. When organic substances are mixed together in varying degrees they take on a melting characteristic that is lower and broader than in its pure form. This property was manipulated in the lab to observe the various melting points of Naphthalene and Biphenyl when the percentage of composition was altered. A

effective method for the purification of organic substances‚ provided that the physical properties of a given compound permits its purification in this manner. Solid organic compounds when isolated from organic mixtures or reactions are seldom pure; they are usually contaminated with small amounts of other compounds called impurities. Solid purification by crystallization is based upon different solubility in a given solvent. Simplest crystallization process is done by dissolving the impure substances

the system might even catch fire. A third possibility is a change of state. As you know‚ matter exists in three states (or maybe four‚ the fourth being a plasma)‚ solid‚ liquid and gaseous. At different temperatures‚ the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In solids‚ the atoms (or molecules) are held firmly together in a closely packed crystal structure. In liquids‚ the crystal has fallen apart rendering the substance shapeless

In a crystal the particles are arranged in an orderly‚ repeating‚ three-dimensional pattern called a crystal lattice. Figure 13.10 shows part of the crystal lattice in sodium chloride. The shape of a crystal reflects the arrangement of the particles within the solid. Figure 13.10 The orderly arrangement of sodium and
