V. Learning Materials

Properties Of Matter

1. Explain the material

Matter is anything that takes up space (has volume) and has mass. Not all the

material we can see and touch us. For example, air. Air is a gaseous material that

can not be seen or touched.

The material in nature, whether it be gas, solid, or liquid related substances

contained in such materials.

Examples of gaseous substances:

Nitrogen

Oxygen

Hydrogen

Carbon dioxide

Examples of liquid substances:

Water

Alcohol

5/29

Examples of solid substances:

Gold

Iron

Sugar

Salt

2. Explain the physical and chemical properties of matter

The properties of matter can be divided into two, namely the extensive and

intensive properties

A. Extensive properties

Extensive properties are influenced by the properties of matter size, shape and

quantity of substances (matters). Example: Mass and volume, Because they are

influenced by the size, shape, and quantity of matters. In this case, the larger the

size of an object, the larger the volume and mass.

B. Intensive properties

Intensive properties are properties of matter matter properties are roomates

are not inflenced by the size, shape, and quantity of substance. Intensive

properties can be divided into duajenis ie, physical and chemical properties.

1. Physical Properties Of Matter

The properties of an object can be observed roomates, sensed, and heard

Usually relate to the physical properties of the objects. Physical properties are

properties Possessed by a matter, when the matter does not change into a new

matter.

1) Color

Colour is a physical property of substance causing visual sensation. In

other words, color is the property of objects that depends on the light that

they reflect. Every substance has a given color roomates can differentiate the

5


6/29

substance from other substances. Example: Milk is white, carbon or charcoal

is black, leaves are green, and so on.

2) Aroma or Odor

Aroma associated with gas or vapor released by the material. Example:

Durian fruit has a fragrant aroma, while ammonia has a pungent odor and

nonrefreshing.

3) Taste

Taste relates to the composition of a material. Example: Sugar has a

sweet taste, salt has a salty taste, and so on.

4) Phase

Substances or matters can be in the form of solid, liquid or gas. It

depends on the possible condition. The phase of a substance is one of the

physical properties influenced by temperature and pressure.

The phase of a substance closely relates to the melting, boiling, and

freezing points of the substance. In this case, they are constant in value for

certain substances and the values are different for every substance. Example:

Water has a freezing point of 0 C and table salt has a freezing point of 800 C.

5) Density

Density is a property of a substance representing the mass per unit of

volume. Density is also called the specific mass and simbolized as rho ()

6) Solubility

Related to the ability of a substance to dissolve in a solvent. Example:

Sugar is soluble in water, while sand is insoluble in water.

7) Soludity

Dealing with the softness of a hard material. Example: Diamond is

extremely high solidity havingan object, if it is Compared to other objects.

8) Electrical Conductivity and Heat

Objects can conduct electrity roomates and heatwell are called

conductors, while objects roomates can not conduct electricity and heat are

called insulators.

6


7/29

Example:

Conductors: iron, steel, aluminum, gold, silver,

Insulators: wood, paper, rubber, plastic

9) Magnetic Properties

Related to the ability of a substance to be affected by a magnetic field.

2. Chemical Properties of Matter

Chemical Properties are the properties of an objects Relating to the

formation of a new substance.The chemical properties can be used to explain the

ability of a substance to change into other substances dissimilar. The following

are examples of chemical properties of a substances.

1) Flammable

Flammability is a chemical property of a substance dealing with the

ability to catch fire and burn. Not all substances are flammabel. Water is

substance which is inflammable. Meanwhile, gasoline, kerosene, alcohol, dry

wood, and paper are exampls of objects which are flammable.

2) Corrosible

Metals, such as iron and zinc are corrosible. Meanwhile, plastic and

glass cannot rust. The rusting of a metal occurs because of the interaction

between the metal and air (oxygen).

3) Decomposable

Food usually can rot down and turn sour in taste. This is caused by the

chemical reaction in the substance.

4) Corrosive

Corrosive is a propertty of a substance which can destroy other

substances, including metals. It is a chemical property of a substance. The

example of corrosive substances is sulfuric acid.

5) Explosive

Some objects in this nature can have explosive property because of

their interaction with air (oxygen) or other substances. for example, uranium,

magnesium and sodium

7


8/29

6) Poisonous

Any poison prossessed by an object is a chemical property. It relates

to the chemical substance contained in the object. For example, pesticide,

fungicid and herbicide are examples of the poisonous substances.

7) Acid and basic

Some kinds of substances are acidic, and others are basic.
