balance. Specific Gravity of each material are then calculated using the values obtained. Guide Questions: 1. Differentiate specific gravity and density. Specific gravity is the ratio of a material’s density with that of water at 4 °C where it is most dense and is taken to have the value 999.974 kg·m-3) and is therefore a relative quantity with no units. Density is defined as mass per unit volume; it has the SI unit kg·m-3 and is an absolute quantity. 2. If 54.96 mL of oil weighs 52.78g. What is

ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans.
