Branches of Chemistry, Classifying matter according to its phases, and Properties of Matter

(June 23 - July 1, 2025, Preliminary (Week 1- Week 3)), 9:26PM

Chemistry

Is the study of matter, its composition, its structure, its properties, the processes that matter undergoes, and the energy changes that accompany these processes.

Analytical Chemistry

Study of the composition if substances and the development of tools used to measure properties of matter.

Qualitative Analysis

Tells you what is present.

Quantitative Analysis

Tells you what or how much is present.

Biochemistry

Study of chemical processes within an related to living organisms.

Studies of Biochemistry

Proteins, Fats, DNA&RNA, Carbs, Lipids, and Enzymes are studies of what?

Inorganic Chemistry

Study of inorganic compounds, typically these that do not have carbon - hydrogen bonds.

Studies of Inorganic Chemistry

Metals, Salts, Gasses, Acid Bases, and Minerals are studies of what?

Organic Chemistry

Study of carbon-containing compounds, Including their structure, properties, and reactions.

It is also the chemistry of life.

Carbon, Hydrogen, sometimes Oxygen, Nitrogen, and others.

What is the most organic compounds containing in the field of Organic Chemistry

Physical Chemistry

The study of how matter behaves on a molecular and atomic level and how chemical reactions occur.

Physical Chemistry

Temperature and heat, Reaction rates, How molecules move, etc. are study of what?

Matter

Fundamental knowledge in chemistry that matter is anything that has mass and volume.

Mass

This is the amount of matter, while volume is the space it occupies.

Properties of Solid

It has a definite shape and volume because its particles are closely packed together in a fixed position.
These particles vibrate and are held together by strong attractive forces. It is also difficult to compress the particles.

Particles of Liquid

It has definite volume and takes the shape of the container.
This flows easily because its particles have enough space and less attractive force.

The spaces in the particles allows to be compressed a little bit.

Particles of Gas

It takes the volume and shape of the container. These particles are far from each other that is why they have the weak attractive force and can flow easily, they occupy the entire space available, the large space in between the particles allows particles to be compressed easily.

Physical Property

Is one that can be observed without changing the compositions of a substance. This include (solid, liquid, and gas), color, solubility, density, melting, and boiling points, viscosity, and conductivity.

Extensive Properties

Or sometimes called Extrinsic properties, Its mass, length, size, and volume depend on the amount of matter or substance that is being measured.
This means that the more matter there is, the greater is its mass, volume, or any one of its properties.

Extensive

This is dependent on the “Matter”.

Intensive Properties

Or Intrinsic properties, this depend on the melting, boiling, and freezing points, and thermal conductivity, This properties may be used to Identify a substance.

Intensive

This is not dependent on the "Matter”.

Chemical Property

are characteristics that can be observed with an accompanying change in the chemical composition of a substance.

Chemical Reactivity

A chemical property may also be described in terms of how a substance reacts with another substance.

Physical Changes

Size, color, density, and mass become different, but its chemical properties remains the same.

Chemical Changes

are those that transform the chemical Identity of matter though chemical reactions, Burning, rotting, ad cooking are some of the common examples.

Pure Substances

Is a form of matter that has a constant composition and distinct properties.

Elements

are said to be the building blocks of matter. It cannot be broken down into simpler substances simply because it is the simplest form of matter, to date there are 118 elements.

Compound

Is composed of 2 or more elements combined chemically in definite proportions.
