Bulk matter represents materials composed of a large assemblage of atoms or molecules, where the behavior of these particles collectively results in distinct properties. The chapter discusses various states of matter, density, pressure, buoyancy, surface tension, viscosity, capillarity, and elasticity, highlighting how these concepts apply in real-world scenarios, such as in hydraulic systems and the behavior of liquids. Additionally, key relationships like relative density and pressures in fluids are clearly defined with essential formulas.

Term: Bulk Matter
Definition: Materials composed of a large number of atoms or molecules, exhibiting properties that emerge from collective particle behavior.
Term: Density
Definition: The mass of a substance per unit volume, calculated with the formula Density = Mass / Volume.
Term: Pressure
Definition: The force applied per unit area, expressed as Pressure = Force / Area.
Term: Buoyancy
Definition: The upward force exerted on an object immersed in a fluid, equal to the weight of the fluid displaced.
Term: Viscosity
Definition: The measure of a fluid's resistance to flow, influenced by temperature and the nature of the liquid.
