Performance Task no. 4.1 Pressure Principle I. Introduction Why is theater seat so much more comfortable than a bicycle seat? One of the main reasons any seat is comfortable is the pressure it exerts on your body. This performance task aims to know the importance and application of pressure. Pressure is defined as the force acting perpendicular to a unit area. It is the result of a force distributed over an area. A theater seat’s large padded seat and back offer a larger area to support your

Mohr Westphal 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
