SCIENCE Density Calculate density‚ and identify substances using a density chart. Density is a measure of the amount of mass in a certain volume. This physical property is often used to identify and classify substances. It is usually expressed in grams per cubic centimeters‚ or g/cm3. The chart on the right lists the densities of some common materials. EQUATION: Densities of Substances Substance Density (g/cm3) Gold 19.3 Mercury 13.5 Lead mass density ϭ ᎏ volume

Density Column What is density? We will be working with many different liquids. Each of the liquids has a different‚ characteristic density. One way to think about density is how thick or heavy an object is. The liquids with lighter densities will float. The liquids with heavier densities will drop to the bottom. You may have noticed that sometimes‚ liquids mix together – this is because the chemicals dissolve in each other. During our experiment‚ the liquids will stay separate because we will

Title : Preparation of a standard solution Aim To prepare a standard solution of potassium hydrogenphthalate which will later be used to standardize sodium hydroxide solution‚ NaOH. Research question How does different molarity of potassium hydrogen phthalate solution which is prepared by dilution process influence the volume of sodium hydroxide‚ NaOH used during titration process until the colourless phenolphthalein indicator solution turns pink where the volume of potassium hydrogenphthalate used

Introduction: Density is defined by its mass per unit volume‚ and is most often written in mathematical terms as; d = m / v Mass is usually given in grams‚ g‚ and volume is given in cubic centimeters‚ g/cm3‚ or‚ grams per milliliter‚ g/mL. Density is not a property that depends upon the amount of substance present. For example‚ one gram of lead and one ton of lead have the same density. Density also does depend on temperature. For instance cold water is denser than warm water;

2. Costing aircraft components A British Aerospace case study Introduction When we think about the cost of an aircraft‚ we tend to think of the cost of buying the product rather than the costs of running it! British Aerospace’s service to the customer does not stop at the aircraft acquisition stage‚ when the aeroplane is sold to the customer. If anything‚ this is when the customer relationship begins. This case study focuses upon the processes involved in costing aircraft components. Given the
