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

whether or not the amount of air inputted into a soccer ball would affect the ball’s travel distance. Along with that‚ we hoped to learn which amount of air would deliver the furthest distance. And potentially with this knowledge‚ those who play the sport‚ will know to what amount they should fill their ball to‚ in order to gain the best performance‚ distance wise. Although results may vary among players. This is just a general observation‚ with a certain and consistent amount of force. The experiment
