7. Properties of Bulk Matter
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.

What we have learnt
- Bulk matter includes solids, liquids, and gases, each with unique properties.
- Density and relative density provide insight into the mass and volume relationship of substances.
- Pressure is a critical concept in understanding fluids and their behaviors.
Key Concepts
- -- Bulk Matter
- Materials composed of a large number of atoms or molecules, exhibiting properties that emerge from collective particle behavior.
- -- Density
- The mass of a substance per unit volume, calculated with the formula Density = Mass / Volume.
- -- Pressure
- The force applied per unit area, expressed as Pressure = Force / Area.
- -- Buoyancy
- The upward force exerted on an object immersed in a fluid, equal to the weight of the fluid displaced.
- -- Viscosity
- The measure of a fluid's resistance to flow, influenced by temperature and the nature of the liquid.
