Properties of matter

Properties of matter Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms. The two properties of matter are: • Mass – amount or quantity of matter • Volume – amount of space occupiedphysical properties – inherent characteristics of … Read more

REM in Toxicology

REM in Toxicology: A Comprehensive Overview Rapid eye movement (REM) sleep is a crucial stage of sleep characterized by brain activity similar to wakefulness, vivid dreaming, and muscle paralysis. While REM sleep is essential for cognitive function, emotional regulation, and memory consolidation, its role in toxicology is less well-understood. However, emerging research suggests that REM … Read more

Electromagnets are magnets made using electricity and so are called temporary magnet since they only … Read more

Valency and Chemical Bonding

Valency Valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or Molecules. The combining power, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in … Read more

Corossion of metals

Corrosion is defined as an attack on a material as a result of chemical, frequently electrochemical reaction, with the surrounding medium. According to this definition, the term corrosion can be applied to all materials, including non-metals. But in practice, the word corrosion is mainly used in Conjunction with metallic materials. Why do metals corrode? Apart … Read more

Oceans: Physical, chemical and biological characteristics

Volcanoes and sea-scarps. This great variety of relief is largely due to interaction of tectonic, volcanic, erosional and depositional processes. At greater depths, the tectonic and volcanic phenomena are more significant processes. Continental Shelf: This is a gentle seaward sloping surface extending from the coasts toward s the open sea. In all, about 7.5% of … Read more

Soil: Physical, chemical and biological properties

Soil consists of rock and sediment that has been modified by physical and chemical interaction with organic material and rainwater, over time, to produce a substrate that can support the Growth of Plants.” Soils are an important natural resource.  They represent the  interface between the lithosphere and the Biosphere – as soils provide nutrients for … Read more
