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.

Preinstructional Planning. During Instruction.

Like the particles of a solid, particles in a liquid are subject to intermolecular attraction; however, liquid particles have more space between them, so they are not fixed in position. The attraction between the particles in a liquid keeps the volume of the liquid constant. The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume.

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.

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.

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:.

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.

Чего ты от меня хочешь. Молчание. Хейл сразу же растерялся, не зная, как истолковать примирительный тон коммандера, и немного ослабил хватку на горле Сьюзан. - Н-ну, - заикаясь начал он, и голос его внезапно задрожал.  - Первым делом вы отдаете мне пистолет. И оба идете со. - В качестве заложников? - холодно усмехнулся Стратмор.

 - Он и есть Северная Дакота. Снова последовало молчание: Стратмор размышлял о том, что она сказала. - Следопыт? - Он, похоже, был озадачен.  - Следопыт вышел на Хейла. - Следопыт так и не вернулся. Хейл его отключил. И Сьюзан принялась объяснять, как Хейл отозвал Следопыта и как она обнаружила электронную почту Танкадо, отправленную на адрес Хейла.

Звук мотора, похожий на визг циркулярной пилы, заставил его повернуться. Парень крупного сложения и прильнувшая к нему сзади девушка въехали на стоянку на стареньком мотоцикле Веспа-250. Юбка девушки высоко задралась от ветра, но она не обращала на это ни малейшего внимания.

Беккер заглянул в телефонный справочник. Оставался последний номер. Конец веревочки.

Но Стратмор смотрел на молодого сотрудника лаборатории систем безопасности.

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.
