Classifying Matter by State02:49

Classifying Matter by State

102.7K
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

127.0K
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?

15.1K
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...

Area of Science:

  • Neuroscience
  • Forensic Psychology
  • Brain Imaging

Background:

  • Homicide represents a significant societal burden, yet the underlying neuroscience remains poorly understood.
  • Existing research offers limited insight into the brain characteristics of individuals who commit homicide.

Purpose of the Study:

  • To investigate brain gray matter differences in incarcerated adult males who committed homicide.
  • To compare these differences with those in non-homicide offenders, including violent and non-violent individuals.

Main Methods:

  • Utilized brain imaging techniques to analyze gray matter volume.
  • Compared brain scans of 203 incarcerated homicide offenders with 605 non-homicide offenders.

Main Results:

  • Homicide offenders exhibited reduced gray matter in brain regions crucial for behavioral control.
  • Significant differences were observed in areas associated with social cognition compared to other offender groups.

Conclusions:

  • This study provides the first evidence of unique brain abnormalities distinguishing homicide offenders.
  • These neurobiological differences may help differentiate individuals who commit homicide from other serious violent and non-violent offenders.
