Chemistry: Easing Life of Humanities
When I was in grade school, we only studied a little about chemistry. As what I
remember on this topic, it is all about matter. Matter is something that has mass and occupies
space. Based on our discussion, matter is made up of atoms and commonly takes the form of
solids, liquids or gases. We also discussed energy. Energy is a phenomena or waves such as light
or sound. On the other hand, we have also discussed that atoms are the smallest unit of matter
that cannot be divided into smaller particles, according to John Dalton. These atoms then
perform as the building block of every element, forming other structures. Unfortunately, we did
not execute any experiments to fulfill the satisfaction of our learning.
With a basic knowledge of Chemistry, I bravely presented myself to this program to help
my knowledge grow more, even though I know that this subject is clearly difficult but
challenging in a good way. Chemistry is the central science in many ways.)It is crucial in
successfully completing this program.)An understanding of chemistry, of enthalpy and entropy
can help to explain so many occurrences in and around us. )Entropy, the order or disorder of a
system, and the degrees of freedom associated with that order or disorder has applications
beyond this course.)
)First, I am not aware that most of the common objects that we deal with every day are
simple to demonstrate that they have mass and take up space. Even though these things cannot be
seen in our eyes without the use of a microscope-for instance, air (and all gases) are invisible in
the eye, they have light masses compared to solids and liquids. With an increase in the order of a
system there is a decrease to the degrees of freedom.)This applies not only to chemical reactions,
but to the world in which we live.)
Chemistry helps me to identify physical properties that we can observe and measure
without changing the)chemical identity)of the sample. Physical properties are used to describe
matter and make observations about it.)Physical properties)include color, shape, position, volume
and boiling point, while chemical properties only reveal themselves when the sample has reacted
with a catalyst.)Examples of chemical properties)include flammability, reactivity and toxicity. It
is important for us to know the properties of matter so that we can easily recognize things
through their mass, volume, weight, density, odor, and color. (Madhusha 2017) – “physical
properties can be observed without changing the chemical composition of a substance whereas
chemical properties can be observed by changing the chemical composition of a substance.”
These are the characteristics that help us to see matter, feel matter, and taste matter.
Energy saving has been an elusive quest for many of us living in urban developed cities.
We need energy for everything in our household and it is one of the earmarks of modern living
and convenience. “We use energy for everything in the home and in the office and basically to
perform daily tasks.” - (Renewable Energy World). In our lives, energy)is a very important entity
in the modern world. We use energy to light our homes, drive our cars, and power our electronic
devices. Energy is essential in our daily lives, especially since most of our work is dependent on
