Classifying Matter by State

103.0K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

The Atomic Theory of Matter

127.7K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

What is Matter?

15.9K
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...

    Summary

    Outdoor air pollution, specifically particulate matter (PM), is linked to allergic rhinitis (AR). This review explores PM composition, AR epidemiology, and the immune mechanisms driving PM-induced allergic rhinitis.

    Area of Science:

    • Environmental Health
    • Immunology
    • Allergy Research

    Background:

    • Outdoor air pollution is a significant global environmental health issue.
    • Particulate matter (PM) exposure is increasingly associated with allergic rhinitis (AR) development and worsening.
    • The precise mechanisms linking PM exposure to AR remain incompletely understood.

    Purpose of the Study:

    • To review the composition of particulate matter (PM).
    • To summarize epidemiological evidence linking PM exposure to allergic rhinitis (AR).
    • To explore potential immune system mechanisms underlying PM-induced AR.

    Main Methods:

    • Literature review of recently published studies.
    • Analysis of PM composition data.
    • Examination of epidemiological findings on PM and AR.
    • Investigation of immunological pathways.

    Main Results:

    • Particulate matter (PM) comprises various components contributing to its adverse effects.
    • Epidemiological studies provide strong evidence for a correlation between PM exposure and allergic rhinitis (AR).
    • Several immune mechanisms, including inflammatory responses and oxidative stress, are implicated in PM-induced AR.

    Conclusions:

    • Particulate matter (PM) is a significant environmental trigger for allergic rhinitis (AR).
    • Understanding the immune mechanisms is crucial for developing targeted interventions against PM-induced AR.
    • Further research into PM composition and immune responses can inform public health strategies.
