Classifying Matter by State02:49

Classifying Matter by State

105.0K
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...

What is Matter?

104.0K
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...

The Atomic Theory of Matter

130.8K
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...

Area of Science:

  • Immunology
  • Gerontology
  • Infectious Diseases

Background:

  • Aging is linked to increased basal inflammatory state and disease susceptibility.
  • Tuberculosis (TB), caused by Mycobacterium tuberculosis (M.tb), disproportionately affects the elderly.
  • Inflammation is a key factor implicated in age-related TB susceptibility.

Purpose of the Study:

  • To review the relationship between lung inflammation and TB susceptibility in the elderly.
  • To elucidate how aging influences the immune response to M.tb infection.
  • To inform the development of age-specific TB prevention and treatment strategies.

Main Methods:

  • Literature review focusing on aging, inflammation, and tuberculosis.
  • Analysis of immunological mechanisms linking inflammation and M.tb pathogenesis in older adults.
  • Synthesis of current evidence on age-related TB outcomes.

Main Results:

  • Growing evidence supports a link between inflammation and disease susceptibility in the elderly.
  • Aging is a significant risk factor for developing and succumbing to TB.
  • Lung inflammation plays a critical role in the susceptibility of older individuals to TB.

Conclusions:

  • Understanding the interplay of inflammation, aging, and M.tb is crucial for effective TB control.
  • Age-specific factors significantly influence TB risk and progression.
  • Targeted interventions for the elderly are needed to combat TB effectively.
