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...

Classifying Matter by State

104.6K
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.

The Atomic Theory of Matter

130.2K
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...

What is Matter?

103.8K
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...

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...

Área de la Ciencia:

  • Salud Pública La salud pública.
  • Gerontología Gerontología.
  • Salud digital La salud digital.

Sus antecedentes:

  • La actividad física (AP) es crucial para la salud de la mediana edad y los adultos mayores.
  • Los adultos latinos son un grupo demográfico creciente que enfrenta desafíos únicos de salud.
  • Las intervenciones digitales ofrecen soluciones escalables para promover la PA.

Objetivo del estudio:

  • Para comparar la efectividad de tres estrategias de personalización de asesores de PA basadas en SMS.
  • Promover la actividad física entre los adultos latinos de mediana edad y mayores insuficientemente activos.
  • Identificar enfoques óptimos de mensajería digital para diversas poblaciones.

Principales métodos:

  • Un diseño de estudio experimental aleatorizado dentro de un ensayo (SWAT, por sus siglas en inglés).
  • 141 participantes recibieron entrenamiento PA basado en SMS.
  • La aleatorización a las condiciones de asesor no personalizado, de sexo coincidente o de elección de sexo.
  • Evaluación a los 12 meses de la PA utilizando el instrumento CHAMPS.

Principales resultados:

  • Todas las condiciones del SMS aumentaron significativamente la AP durante 12 meses.
  • Los asesores no personalizados y de elección de sexo produjeron mayores aumentos de MVPA que los asesores de sexo emparejado.
  • Los análisis específicos por sexo mostraron ganancias significativas de MVPA para los hombres tanto en condiciones no personalizadas como en condiciones de elección de sexo.
  • Para las mujeres, solo la condición no personalizada mostró aumentos significativamente mayores de MVPA que el sexo emparejado.

Conclusiones:

  • Los asesores de SMS no personalizados y de elección de sexo son efectivos para aumentar el MVPA en esta población.
  • Adaptar la mensajería digital a las preferencias de los participantes puede mejorar la efectividad de la intervención.
  • Los hallazgos apoyan la escalabilidad de las intervenciones de AP digital para comunidades con escasos recursos.
