Particulate vs. Particle — What's the Difference?

Tiny solid or liquid particles suspended in air or liquid, often posing health risks.

A small piece of matter, with applications in physics, chemistry, and everyday language.

Used to describe the collective presence of fine particles in environmental contexts.

Can refer to components of atoms, such as electrons, protons, and neutrons, in physics.

Can be composed of various materials, including dust, pollen, soot, and smoke.

In everyday language, it can describe small, visible objects or materials.

Its impact is studied in relation to respiratory health, visibility, and environmental effects.

Its study is crucial in understanding the composition and properties of materials.

Often associated with pollution and its measurement, particularly in air and water.

Used metaphorically to describe tiny amounts or insignificant quantities.

Of, relating to, or formed of minute separate particles.

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object to which can be ascribed several physical or chemical properties, such as volume, density, or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials.

A minute separate particle, as of a granular substance or powder.

A very small piece or part; a tiny portion or speck.

Often particulates Particulate matter

A very small or the smallest possible amount, trace, or degree

Composed of separate particles.

A body whose spatial extent and internal motion and structure, if any, are irrelevant in a specific problem.

(genetics) Pertaining to heritable characteristics which are attributable discretely to either one or another of an offspring's parents, rather than a blend of the two.

See elementary particle.

Any solid or liquid in a subdivided state, especially one that exhibits special characteristics which are negligible in the bulk material.

See subatomic particle.

To particularize.

An uninflected item that has grammatical function but does not clearly belong to one of the major parts of speech, such as up in He looked up the word or to in English infinitives.

Having the form of a particle.

In some systems of grammatical analysis, any of various short function words, including articles, prepositions, and conjunctions.

Referring to, or produced by, particles, such as dust, minute germs, etc.

(Ecclesiastical) A portion or fragment of the Eucharistic host.

Composed of particles; finely divided.

(Archaic) A small part of something written, such as a clause of a document.

Matter composed of particles; - often used in the pl.; as, the quantity of particulates in auto exhaust is strictly regulated.

A very small piece of matter, a fragment; especially, the smallest possible part of something.

A small discrete mass of solid or liquid matter that remains individually dispersed in gas or liquid emissions (usually considered to be an atmospheric pollutant)

(physics) Any of various physical objects making up the constituent parts of an atom; an elementary particle or subatomic particle.

Composed of distinct particles

(linguistics) A part of speech that has no inherent lexical definition but must be associated with another word to impart meaning, often a grammatical category: for example, the English word to in a full infinitive phrase (to eat) or O in a vocative phrase (O Canada), or as a discourse marker (mmm).

(linguistics) A part of speech which cannot be inflected.

(Christianity) In the Roman Catholic church, a crumb of consecrated bread; also the smaller breads used in the communion of the laity.

A little bit.

A minute part or portion of matter; a morsel; a little bit; an atom; a jot; as, a particle of sand, of wood, of dust.

Any very small portion or part; the smallest portion; as, he has not a particle of patriotism or virtue.

A crumb or little piece of consecrated host.

A subordinate word that is never inflected (a preposition, conjunction, interjection); or a word that can not be used except in compositions; as, ward in backward, ly in lovely.

An elementary particle.

(nontechnical usage) a tiny piece of anything

A body having finite mass and internal structure but negligible dimensions

A function word that can be used in English to form phrasal verbs

A particle is a small piece of matter, which can range from subatomic components like electrons to small visible objects like dust grains.

Some particulate matter, like dust and smoke, can be visible, but many particulates, especially those of concern for health, are microscopic and not visible to the naked eye.

Particulate matter refers to a mixture of tiny solid or liquid particles suspended in air, which can be harmful to health and the environment.

Particulates are often measured by their concentration in the air or water, using units like micrograms per cubic meter, and categorized by size (e.g., PM2.5, PM10).

"Particulate" often describes fine particles in environmental contexts, like air pollution, while "particle" is a broader term used in various scientific fields and everyday language.

Particle size can affect the properties and behavior of materials, as well as the health impacts of particulates, with smaller particles often posing greater risks.

Fields like environmental science, public health, and atmospheric chemistry study particulate matter, especially its sources, effects, and control.

Not all particles are considered particulates; "particulate" specifically refers to small particles suspended in a medium like air or water, often with implications for health and environment.

Yes, particulate matter can come from both natural sources, like volcanoes and wildfires, and human-made sources, like combustion engines and industrial processes.

Environmental regulations typically set limits on particulate emissions and concentrations in the air, aiming to protect public health and the environment.

Yes, particles play a crucial role in various technologies, from semiconductor manufacturing to drug delivery systems in medicine.

Common methods include air filtration systems, emission controls on vehicles and industrial processes, and regulations limiting the release of particulates.

Understanding the properties and interactions of particles is crucial in material science for developing new materials and improving existing ones.

Yes, particulate matter can affect the climate by influencing cloud formation, altering rainfall patterns, and affecting the Earth's radiative balance.

Particles are important in atmospheric science for understanding phenomena like cloud formation, air quality, and climate change.
