Essay on States of Matter and How Matter Changes

The objective of the experiment “Keeping it Liquid” was to figure out what it takes to keep a compound in a liquid form which caused a phase change. A phase change is when a substance changes from one state or phase to another. There are three main phases that normally occur and they are called Evaporation, Deposition, and Melting. Evaporation is where a liquid changes to a gas. An example of evaporation is when water drops form on the glass of a cold drink on a warm day. Deposition is where a gas vapor goes directly into the solid phase without becoming a liquid first. An example of Deposition often occurs on windows during the winter months. While Melting is where a solid turns into a liquid. Melting occurs when ice turn into a liquid when

Solids are composed of atoms, ions or molecules arranged in a pattern that is represented in three dimensions, they all have a definite shape and volume, they are virtually incompressible and they do not flow readily.

The composition of a pure substance is constant, and thus pure substances have characteristic physical properties that do not change and this is why we are able to separate each element in this lab experiment. Examples of physical properties that can be used to describe pure substances include solubility, conductivity, magnetism, density, boiling point, and melting point.

Matter is often defined as mass that can be physically observed by the senses, it can be measured scientifically and is tangible , it could be said the material world unlike aspects of social worlds is less abstract and easier to define, for example a building which comprises of bricks, wood, metal and other materials built into a specific shape compared to a community which can relate to people of the same place or shared values or interests or all. That is not to say that matter just is, it too can have agency and varying meanings dependent upon the

Do you know what state of matter slime is? It can be picked up like a solid, but it also doesn’t take shape like a liquid, so what is it exactly? Slime is actually a non-Newtonian fluid —a substance that acts like both solid and liquid.

Matter is defined by Lucretius as a primordial entity free of void and decay; they are the atoms that create entities. Atoms and primordial entities are synonymous with each other: the solidity of matter is called “procreant atoms, matter, seeds of things, or primal bodies, as primal to the world” (107-108). Lucretius uses all these words, emphasizing the simplicity of his philosophy. This simplicity is explained as he declares: “primal bodies are solid, without a void” (596). Because he believes that all entities are composed of primal bodies and a void, the primal body must be free of any void, thus giving substance to the object. He declares that entities are composed: “partly primal germs of things, and partly unions deriving from the primal germs” (566-567). This definition states that all matter consists of atoms, which, when combined, form molecules. Molecules, as defined by science, are the “unions” of atoms. This scientific principal is further explained: “So primal germs have solid singleness, which tightly packed and closely

Glass has a variety of unique properties. Glass is hard, very brittle, a good insulator, and does not react to other chemicals easily. In addition to this, glass is considered an amorphous solid. This means that the molecular structure of glass is mostly random. This is because in the process of making glass, glass is cooled so quickly that it does not have time to form or create a structure at the molecular level. This process is known as quenching.

Liquid: having a consistency like that of water or oil, flowing freely but of a constant volume.

What is a pure substance? The definition of a pure substance is a substance that is made up of only one particle. For example water and sugar are pure substances. In a pure substance, the particles are always the same and are evenly spaced.

The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.

5) List the three common states of matter in order of highest potential to lowest.

At a temperature slightly above absolute zero, it is transformed into helium II, also called superfluid helium, a liquid with unique physical properties. It has no freezing point, and its viscosity is apparently zero; it passes readily through minute cracks. Helium-3, the lighter helium isotope, which has an even lower boiling point than ordinary helium, exhibits different properties when liquefied.

Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing the composition of the subject. Descriptive words that would help to identify a substance’s physical property include hard, soft, brittle, flexible, heavy, and light just to name a few.

More recently, distinctions between states have been based on differences in molecular interrelationships. Solid is the state in which intermolecular attractions keep the molecules in fixed spatial relationships. Liquid is the state in which

An increase in internal energy is required to convert a solid to a liquid,. Conversely, a reduction in internal energy can cause liquids to freeze or solidify. When heat is added to a solid or a liquid, the temperature of the sample does not necessarily rise. During a phase change, heat is added to the sample without an increase in temperature. Heat absorbed or released as the result of a phase change is called latent heat. There is no temperature change during a phase change, thus there is no change in the kinetic energy of the particles in the material. Latent heat is an intensive
