In Chemistry, you will find out, that it is a fundamental part of our growth, as humans, if we don’t study, the fundamentals, of Chemistry, then you will not be able, to fundamentally grow, in an environment, which is full of molecules.

These molecules, are all around us; therefore, it would be a smart thing, to understand the molecules around us, or have some type of idea, about chemistry.

In today’s article, we are going to be talking about, some fundamental definitions, which are found in the science of chemistry.

Let’s begin with the properties, of matter, which is anything that, has mass and volume, such as students, planets, air and glass.

The composition of matter, is a particular interest of most chemist, because they are able to study, and analyze, the types and amounts of simpler substances, which make up the matter.

A matter, which has a defined fixed composition, is known as a substance.

When we observe, study and analyze the properties of matter, we can learn a lot about matter; such as the characteristics, which give a substance, its unique identity.

For example, blood type, finger prints, hair, height, eye color and weight, can be used to identify a person, because these are some of the characteristics of a person, which can identify that person.

In chemistry, by observing a substance’s physical and chemical, distinct types of properties, you’ll be able to identify a substance.

Matter undergoes two types of changes, and they can either be physical change or chemical change.

Properties, which a substance, shows by itself, without changing into another substance, or without interacting with another substance, are known to be the physical properties, of matter.

Properties, such as color, melting point, electrical conductivity, and density, are some of the properties, considered to be the physical properties, of matter.

When a substance’s physical form is altered and not its composition, then, we can note that a physical change has occurred, to that substance.

Changes, which occurs, in different, physical properties, are said to be physical changes; such as the changes, we notice in water, when it goes from a solid, to its liquid state.

We can say that the, hardness, density and ability to flow (which are physical properties) have changed, but we are still dealing with water.

A physical change, in a substance, does not change the composition of its particle, which means that water is still water, in its solid and liquid state.

A chemical change on the other hand, it’s totally different from a physical change, let’s see how different they are.

When a substance changes into another substance, or interacts with other substances, it is said that the chemical properties of that substance have changed; therefore, a chemical change, has occurred.

Reactivity with acids, flammability and corrosiveness, are some of the examples, that a substance shows, in its chemical properties, when it undergoes a chemical change.

When a substance is converted, into a different substance, a chemical change or chemical reaction, is said to have occurred.

A good example is water, if you pass electricity through water, it will change its composition.

Meaning that water will now become, hydrogen and oxygen, which are two totally different substances, then water.

Chemistry is fun to learn unfortunately this is where we stop, but don’t stop surfing the website, and keep learning about chemistry.
