March 2‚ 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a

Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules

Visualising solid shapes Solid shapes A solid shape is a 3-dimensional shape‚ one that has depth‚ width and breadth. Examples: pyramids‚ cubes and spheres .(such as a ball) One - Dimensional Shapes A figure that has only length is called One– Dimensional Figure. For example line‚ line segments‚ ray‚ etc. One-dimensional figure does not have any width or thickness. Two – Dimensional Shapes The shape of an object located in some space is a geometrical description of the part of that space occupied

Solid Wastes Management BASURA‚ GARBAGE‚ GOMI‚ ORDURES‚ AFVAL‚ SPAZZATURA— whatever people call it‚ solid waste is a problem that must be properly managed. While it is generally understood that proper waste management helps protect human health and the environment and preserve natural resources‚ many do not realize that solid waste also impacts climate change. The manufacture‚ distribution‚ and use of products—as well as the disposal of the resulting waste—all result in emissions of atmospheric

column loads that require thicker foundation slab considering economy of the structure. Both beams cast monolithically with raft slab. Solid raft foundation The unified solid raft foundation is the most simple foundation form and its formwork assembling as well as its reinforcement implementation do not require hard labor. Solid raft foundation In the solid raft foundation‚ there is only one unified foundation slab. The foundation slabs are reinforced with two wire meshes‚ one placed at the

Dana Kearse Key Terms Bankruptcy system – resolve effects of financial failure Composition agreement – an agreement between debtor and creditors for the repayment of debt Debt collection- collects assets and distributes proceeds to the multiple creditors. Debtor relief – legal relief from debt Discharge- forgiving the debt. Exemption – is property that a debtor may protect from seizure by creditors. Assignment for the benefit of creditors- takes place when a debtor‚ assigns its assets

EXERCISE 9 - Mechanical properties of solid and fluid mechanics 1. A stainless-steel wire of length 3.1 cm and a diameter of 0.22 mm. If it is stretched by 0.10 mm‚ find the tension of the wire. The Young’s modulus for stainless steel is 18 × 1010 Pa. 22 N 2. Determine the elongation of the rod i Figure 1 if it is under a tension of 5.8 × 103 N. Young’s Modulus: Copper‚ 11.0 x 1010 Nm-2‚ Aluminium 7.0 x 1010 Nm-2 1.9 cm 3. Air is trapped above liquid ethyl alcohol in

Experiment 2 – Identification of Inorganic Solids Jesse Galina CHM 101 Lab Monday October 1‚ 2012 Unknown Solid – 2 Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water‚ the solution turned pink which agrees with the statement that the cation was Co
