the particulate nature of matter

Intensive investigation by scientists over the years led to the development of a mental model (the minuscule particles couldn't be actually seen at that time) known as 'dynamic particle model'. All matter is assumed to be made up of particles that are very small, which may be atoms, mole..

Brownian motion can be demonstrated simply by releasing some smoke particles from burning cord into a small glass container and putting a cover plate to seal the smoke and air into the cel..

Particulate refers to 'finely divided solid or liquid particles suspended in air'. The size of particulates varies from about 0.0002 to about 500 (1 = 10 - 4 cm). In the polluted air, the number of particulate particles is as high as 10 1 1 per m 3 . In urban areas the..

Dust particulates originate from natural, domestic, industrial or agricultural sources. These are thrown into the atmosphere by blowing of dust by wind, mining operations etc. Rapid deforestation leading to exposed soil cover and erosion has increased this type of pollution. ..
