1.For this week, we continued our EOY revision. We covered: 1) Mass Weight & Density – We distinguished mass and weight, understanding that they are related to one another by the gravitational field strength. We then went on to cover the concept of density, where we revisited the important applications of density. 2) Chemical Composition – We revised the properties of elements compounds & mixtures. We also covered the properties of compounds & mixtures, as well as how to interpret the important information from a periodic table. 3) Solutions & Suspensions – We covered the characteristics of two types of mixtures, solutions & suspensions. We then ended off our lesson by covering the factors affecting solubility of solutions.
