- 10 Examples of Solids, Liquids, Gases, and Plasma
Gases have three characteristic properties: 1 they are easy to compress, 2 they expand to fill their containers, and 3 they occupy far more space than the liquids or solids from which they form.
Solids and liquids are collectively called condensed phases because their particles are in virtual contact. The two states share little else, however. In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough therm al energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume. Most solids are hard, but some like waxes are relatively soft.
Properties of Matter: Liquids
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion , releasing heat , light , and various reaction products. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Fire in its most common form can result in conflagration , which has the potential to cause physical damage through burning.
All properties of matter are either extensive or intensive and either physical or chemical. Extensive properties, such as mass and volume, depend on the amount of matter that is being measured. Intensive properties, such as density and color, do not depend on the amount of matter. Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are:.

Matter is categorized as a gas, a liquid and a solid on the basis of the physical state. All soils contain mineral particles, organic matter, water and air. In condensed matter physics, a Bose—Einstein condensate BEC is a state of matter also called the fifth state of matter which is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero What Is Matter?.

Fire is a manifestation of uncontrolled combustion. It involves combustible materials which are found around us in the buildings in which we live, work and play, as well as a wide range of gases, liquids and solids which are encountered in industry and commerce. They are commonly carbon-based, and may be referred to collectively as fuels in the context of this discussion. Despite the wide variety of these fuels in both their chemical and physical states, in fire they share features that are common to them all. Differences are encountered in the ease with which fire can be initiated ignition , the rate with which fire can develop flame spread , and the power that can be generated rate of heat release , but as our understanding of the science of fire improves, we become better able to quantify and predict fire behaviour and apply our knowledge to fire safety in general. The purpose of this section is to review some of the underlying principles and provide guidance to an understanding of fire processes. Combustible materials are all around us.
Initially the fuel may be in the form of a gas, liquid, or solid at the ambient NFPA ~41, Fire Hazard Properties of FIammable Liquids, Gases, and Volatile.
The four main states of matter are solids, liquids, gases, and plasma. Giving examples of solids , liquids, gases, and plasma is a common homework assignment in chemistry, physics, and physical science classes. Naming examples is a good way to start thinking about the properties of the states of matter. A solid is a form of matter that has a defined shape and volume. Atoms and molecules in most solids are packed together more closely than in the other states of matter with some exceptions.

Ищите. Джабба окончательно убедился: директор рискнул и проиграл. Шеф службы обеспечения систем безопасности спустился с подиума подобно грозовой туче, сползающей с горы, и окинул взглядом свою бригаду программистов, отдающих какие-то распоряжения. - Начинаем отключение резервного питания. Приготовиться.
Потеряв ориентацию, двигалась, вытянув перед собой руки и пытаясь восстановить в памяти очертания комнаты. Споткнулась о мусорный бачок и едва не наткнулась на кафельную стенку. Ведя рукой по прохладному кафелю, она наконец добралась до двери и нащупала дверную ручку. Дверь отворилась, и Сьюзан вышла в помещение шифровалки. Здесь она снова замерла. Все выглядело совсем не так, как несколько минут. ТРАНСТЕКСТ выступал серым силуэтом в слабом сумеречном свете, проникавшем сквозь купол потолка.
