         <description><![CDATA[You can use the triangle to calculate measurements of mass, density and volume. Work out the density of a 4 kg lump of metal with a volume of 1.25 m3. Density = Mass ÷ Volume, so: 4 ÷ 1.25 = 3.2 kg per m3.]]></description>

         <description><![CDATA[There are several differences between a physical and chemical change in matter or substances. A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.]]></description>

         <description><![CDATA[Neutralization. A special property of acids and bases is their ability to neutralize the other's properties. In an acid-base (or neutralization) reaction, the H+ ions from the acid and the OH- ions from the base react to create water (H2O). Another product of a neutralization reaction is an ionic compound called a salt]]></description>
