Classifying Matter by State02:49

Classifying Matter by State

102.8K
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

127.2K
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...

States of Matter

Solids, liquids, and gases are the three states of matter commonly found on Earth. A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of its container, except it forms a flat or slightly curved upper surface when acted upon by gravity. Both liquid and solid samples have volumes nearly independent of pressure. A gas takes both the shape and volume of its container.
Scientists have discovered a fourth state of matter, plasma, that occurs naturally in the interiors...

What is Matter?01:13

What is Matter?

15.3K
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
This summary is machine-generated.

Clinical uncertainty surrounds infant nutrition. Early diet in preterm infants impacts short-term physiology but not reliably clinical outcomes. Longer-term developmental effects are under investigation.

Area of Science:

  • Neonatal nutrition
  • Pediatric development
  • Clinical trial research

Background:

  • Multiple infant dietary regimens highlight clinical uncertainty in neonatal care.
  • Decisions on infant nutrition often rely on short-term physiological data rather than clinical outcomes.
  • Few studies have prospectively evaluated the long-term impact of early diet on infant development.

Purpose of the Study:

  • To analyze the reasons for clinical uncertainty in feeding low birthweight infants.
  • To assess the relationship between early diet, short-term physiological responses, and long-term clinical outcomes in preterm infants.
  • To investigate the potential lasting effects of neonatal diet on infant development.

Main Methods:

  • Analysis of data from multicentre outcome trials involving nearly 1000 preterm infants.
  • Random assignment of infants to different early dietary regimens.
  • Short-term assessment of infant physiology (nutrient accretion, growth, metabolism) and preliminary 18-month follow-up for developmental outcomes.

Main Results:

  • Early diet significantly influences short-term infant physiology but has limited predictive value for clinical outcomes.
  • Preliminary follow-up data suggest potential persistent effects of neonatal diet on motor and mental development and growth.
  • Physiological responses in the neonatal period do not reliably predict long-term clinical outcomes.

Conclusions:

  • Short-term physiological measures are insufficient for guiding neonatal dietary choices for optimal clinical outcomes.
  • Neonatal diet may have significant and lasting consequences for preterm infant development.
  • Further investigation is required to understand the long-term implications of early nutrition in preterm infants.
