matter

[Virtual Presenter] Good morning everyone. Today I will be discussing the essential properties of matter and how they can be classified as either extensive or intensive. By the end of this presentation, I'm confident that you will have a better understanding of this topic. Let's begin..

[Audio] Matter is a fundamental aspect of the universe, and possesses measurable properties. Physical properties are those that can be observed without altering the substance itself, like color, melting and boiling points, density, and mass. Chemical properties on the other hand describe the way a substance interacts with components like air, acid, base, water, and others. Intensive physical properties are independent of the amount of the substance in use, while extensive physical properties vary depending on the amount of the substance used, such as mass, volume, length, and shape..

[Audio] Matter is an incredibly interesting concept that is anything that has mass, takes up space, and can exist in three states - solid, liquid, and gas. Various physical properties like length, density, colour, volume, mass, elasticity, malleability, melting point, hardness, and odour can be measured in order to differentiate one material from another. For example, an apple and an orange can be easily distinct from one another through their colour. With knowledge of the physical properties of matter, we can gain a better understanding of our environment..

[Audio] Matter is defined as anything that exists in the physical world, with mass, occupying space, and made of atoms. Properties for describing matter can be divided into two types: extensive, which depend on the amount of matter, such as mass, volume and weight; and intensive, which does not depend on the amount, like temperature, concentration, boiling point, luster, entropy and colour. Knowing if a property is intensive or extensive is essential when correctly describing matter..

[Audio] Matter has both intensive and extensive properties. Intensive properties are those that are independent of the amount of matter present. Examples of intensive properties are pressure and temperature. On the other hand, extensive properties are dependent on the amount of matter in a certain sample. Mass and volume are examples of extensive properties. So, intensive and extensive properties help us to better understand how matter behaves in different states." Matter is an important concept in science and can exist in three states: solid, liquid, and gas. But matter has both intensive and extensive properties. Intensive properties are properties that are independent of the amount of matter present, like pressure and temperature. Extensive properties, however, depend on the amount of matter in a sample, such as mass and volume. Understanding these properties helps us better understand how matter behaves in different states..

[Audio] Matter is characterized by its mass, its volume, and its ability to exist in three different physical forms: solid, liquid, and gas. Additionally, matter possess certain properties like reactivity, flammability, toxicity and acidity. Reactivity is the ability of a substance to interact or combine with other substances, whereas flammability gauges how easily a material will ignite and burn. Toxicity is the degree to which a material is poisonous, while acidity is the ability of a material to react to an acid. Knowing and understanding these characteristics is essential to comprehending the nature of matter..

[Audio] Matter is a fundamental concept in science and can exist in four states: solid, liquid, gas, and plasma. Solid matter has molecules closely packed together, liquid matter is nearly incompressible and takes the shape of its container, gas has particles far apart and fast-moving, and plasma is made up of electrically charged particles. Melting, vaporization, and ionization are all processes in which matter can change between its different states. Knowing the different states of matter can help us better understand how the world works." Matter is an important concept in science and it can exist in four different states: solid, liquid, gas, and plasma. The molecules in a solid are very tightly packed, and a liquid can take on any shape of its container while still maintaining a constant volume. Gas has particles far apart and that move quickly, and plasma is made of charged particles. Lastly, Melting, vaporization, and ionization are all processes that can cause matter to change its state. Understanding the different states of matter can help us to understand more about the world around us..

[Audio] Matter exists in three states: solids, liquids, and gases, but the plasma state is a bit different. Plasma is a combination of positive and negative particles and is sometimes referred to as the fourth state of matter. It consists of particles such as electrons and ions, distinguished by its unique properties determined by electromagnetic forces. These forces can act over long distances, allowing a plasma to act as a collective unit, like a fluid, despite its particles not colliding with each other. Additionally, plasma does not have a fixed shape or volume and exhibits the lowest intermolecular forces out of the three commonly known states of matter..

[Audio] Matter is an essential element of our universe, being the basic constituent of all objects on Earth - from desks and chairs to the air we breathe. Matter can take on three primary forms - solid, liquid, and gas - and it may also exist as a combination of all three. While dark matter and dark energy cannot be observed, it is widely accepted that they are two components of the universe that make up a significant portion of it; together, ordinary matter, dark matter, and dark energy constitute 4.6%, 26.8%, and 68.3% of the universe respectively..

[Audio] Dark matter is a mysterious component of our universe that cannot be seen directly. It was first hypothesized by Fritz Zwicky in 1933, based on his observations of the Coma Galaxy Cluster. Dark matter makes up about 30.1% of the matter-energy composition of the universe, the rest being dark energy and ordinary visible matter. Dark matter does not interact with the electromagnetic field, rendering it undetectable since it does not absorb, reflect or emit radiation. Its presence, however, is inferred from its gravitational effects and its influence on the structure and evolution of the universe. Dark matter remains an enigmatic component of our universe that scientists are still trying to unravel..

[Audio] Antimatter particles have the same charge as matter particles, but of opposite sign - an antiproton is negatively charged and an antielectron (positron) is positively charged. Computer technology has revolutionized our world, enabling us to do things that were once thought to be impossible..

[Audio] Atoms and molecules that have mass and take up space make up matter. Matter can be in the form of solid, liquid, or gas. Various units are used to measure matter such as temperature in Kelvins, length in meters, mass in kilograms, weight in Newtons, volume in cubic meters, density in kilograms per cubic meter, and pressure in Pascals. This knowledge helps us understand our world better..

[Audio] Matter is anything that has mass, occupies a space, and can exist in three states; solid, liquid and gas. Fundamental particles that make up matter include electrons, photons, neutrons, protons and gluons. Electrons are subatomic particles with a negative charge. Photons are responsible for the electromagnetic force between leptons and quarks. Neutrons and protons have a mass of one atomic mass unit and commonly bind together to form atoms. Gluons are particles that are responsible for the strong force between quarks, thus helping form protons and neutrons..

[Audio] Matter is any substance that has mass, takes up space, and can exist in three basic states: solid, liquid, and gas. Muons are elementary particles, similar to electrons, but with a much greater mass. They are classified as leptons, which are particles that do not undergo strong interactions. Quarks are also elementary particles and a fundamental constituent of matter. Quarks join together to form composite particles, such as protons and neutrons. Charged leptons and neutral leptons are also included in this classification. Examples of leptons are electrons, muons, taus, and neutrinos. The up and down quarks are types of elementary particles and a major constituents of matter. The down quark is the second-lightest of all quarks, and the up quark is the lightest of all quarks. Together they form neutrons and protons of atomic nuclei. In conclusion, matter exists in three basic states and contains a number of elementary particles like muons, leptons, quarks, and down quarks and up quarks that contribute to its structure. Thank you for your attention..
