You can find two classes of properties:
matter can exist in 3 different states.
Liquid state: possesses the property of flowing to adopt the
shape of its container.
Solid state: rigid, possesses a definite shape.
Gaseous state: takes both the shape and volume of its
container. Gases are quickly compressible and capable of infinite expansion.
properties can be noticed and measured without altering the identity of the
cannot be observed and measured only by altering the identity of the substance.
properties explain a substance's ability to go through chemical change.
Understanding the Properties of Matter
The science of chemistry is mostly concerned with the
understanding and classification of matter. This understanding normally begins
with careful observations. What does a certain sample of matter seem like? Is
it a solid, liquid or gas? Is it hard or soft? Is it shiny or dull? These types
of questions are where we will start our study of matter and its properties.
Matter is regarded as anything that has mass and uses up
space. Matter can be best understood with regards to its properties. Some
properties of matter can be determined without changing the identity of the
matter and it is there that we will start.
Silver and ordinary table salt, are 2 examples of chemical
substances. A pure substance is actually matter that has a uniform and definite
composition. All examples of pure substances have the same properties.
A physical property is actually
a characteristic of a substance that can be observed or measured without
altering the identity of the substance. For instance, silver is a shiny metal
that conducts electricity perfectly. It can be also molded into thin sheets, a
property referred to as malleability. These are all physical properties of
