Matter is made up of..
Answers
Answer:
matter is made up of tiny particles called atoms and molecules. Students observe a solid metal hammer and a nail and view a molecular model animation of the particles in a solid.
Answer:
In classical physics and general chemistry, the matter is any substance that has mass and takes up space by having volume.[1]:21 All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in every day as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles (or combination of particles) that act as if they have both rest mass and volume. However, it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound.[1]:21[2] Matter exists in various states (also known as phases). These include classical everyday phases such as solid, liquid, and gas – for example, water exists as ice, liquid water, and gaseous steam – but other states are possible, including plasma, Bose-Einstein condensates, fermionic condensates, and quark-gluon plasma.[3]
Usually, atoms can be imagined as a nucleus of protons and neutrons, and a surrounding "cloud" of orbiting electrons which "take up space".[4][5] However, this is only somewhat correct because subatomic particles and their properties are governed by their quantum nature, which means they do not act as everyday objects appear to act – they can act like waves as well as particles and they do not have well-defined sizes or positions. In the Standard Model of particle physics, the matter is not a fundamental concept because the elementary constituents of atoms are quantum entities which do not have an inherent "size" or "volume" in any everyday sense of the word. Due to the exclusion principle and other fundamental interactions, some "point particles" known as fermions (quarks, leptons), and many composites and atoms, are effectively forced to keep a distance from other particles under everyday conditions; this creates the property of matter which appears to us as matter taking up space.
For much of the history of the natural sciences, people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, independently appeared in ancient Greece and ancient India among Buddhists, Hindus and Jains in 1st-millennium BC.[6] Ancient philosophers who proposed the particulate theory of matter include Kanada (c. 6th–century BC or after),[7] Leucippus (~490 BC) and Democritus (~470–380 BC).[8]
A definition of "matter" more fine-scale than the atoms and molecules definition is: matter is made up of what atoms and molecules are made of, meaning anything made of positively charged protons, neutral neutrons, and negatively charged electrons.
