Physical and Chemical Properties. All substances have properties that we can use to identify them. For example we can idenify a person by their face, their voice, height, finger prints, DNA etc.. The more of these properties that we can identify, the better we know the person. In a similar way matter has properties - and there are many of them. There are two basic types of properties that we can associate with matter.
What are Physical Properties and Changes? Physical Properties:. Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density , solubility, polarity, and many others.
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:.

Manufacturing Defects Metals Polymers Composites. Physical and Chemical Properties. The difference between a physical and chemical property is straightforward until the phase of the material is considered. When a material changes from a solid to a liquid to a vapor it seems like them become a difference substance. However, when a material melts, solidifies, vaporizes, condenses or sublimes, only the state of the substance changes. Consider ice, liquid water, and water vapor, they are all simply H 2 O.
A physical property is any property that is measurable , whose value describes a state of a physical system. Physical properties are often referred to as observables. They are not modal properties. A Quantifiable physical property is called physical quantity. Physical properties are often characterized as intensive and extensive properties. An intensive property does not depend on the size or extent of the system, nor on the amount of matter in the object, while an extensive property shows an additive relationship. These classifications are in general only valid in cases when smaller subdivisions of the sample do not interact in some physical or chemical process when combined.

Physical properties do not change the chemical nature of matter. Special types of physical changes where any object changes state, such as when water freezes or evaporates, are sometimes called. Thanks for watching our Academy review channel! Matter can be classified in different ways using physical and chemical properties. These properties are called Physical properties and Chemical properties.
Before viewing an episode, download and print the note-taking guides, worksheets, and lab data sheets for that episode, keeping the printed sheets in order by page number. During the lesson, watch and listen for instructions to take notes, pause the video, complete an assignment, and record lab data. See your classroom teacher for specific instructions. Chemistry is the study of matter, its composition and the changes it undergoes. During this semester, you will be introduced to the scientific method used to study matter and will be given the mathematical tools you will need for the remainder of the course.

Угадать ключи к ним невозможно. Если вы думаете, что можно ввести шестьсот миллионов ключей за сорок пять минут, то пожалуйста. - Ключ находится в Испании, - еле слышно произнесла Сьюзан, и все повернулись к. Это были ее первые слова за очень долгое время. Сьюзан подняла голову. Глаза ее были затуманены.
Ты сошла с ума! - крикнул в ответ Хейл. - Я вовсе не Северная Дакота! - И он отчаянно забился на полу. - Не лги, - рассердилась Сьюзан.
