Chemistry Basics

Chemistry is said to be an inviting subject. Of course, many of us are grappling to memorize the periodic table: the atomic amount and mass, yet for some they deem it as practice.

I love Chemistry that is why when I was in high school I was a member of the Science Club. We had experiments, and we asked a lot of questions about the "Why's of Things." Maybe, I was just too curios and curious in all of God's creations and gifts to man.

Check this:

Atoms are the construction blocks of chemistry. They are the smallest component of anything; molecules.

Chemists study the behavior and characteristics of substances. These are called the properties of a substance. All substances are made ups of tiny particles called atoms. A substance the size of a pinhead contains billions of atoms.

An atom is the smallest unit of a substance that can exist and keep the properties of that substance. There are over 100 separate types of atoms, known as elements. Each element has its own chemical name and a shortened name known as a chemical symbol.

Most symbols are abbreviations of the chemical name, like h for hydrogen. However, some symbols come from other languages. For example, the chemical sticker for gold, Au, comes from its Latin name, aurum.

The states of matter define how things move and how we can differentiate one substance from another.

Substances are divided into solid, liquids or gases. These are known as the states of matter. It is potential for a substance to move from one state to another. It is known as a turn of state. It normally occurs because of a turn in the power of a substance as a supervene of heating or cooling.

Many substances can exist in more than one state. In a chemical reaction, it is leading to know in which state the varied chemicals are being used. This is done by placing the sticker (s) for solid, (l) for liquid, and (g) for gas after the name of the substances.

Evidence of molecules

The molecules in liquids and gases are continually inviting in a wholly random way. This can be seen when smoke molecules are viewed under a microscope. They move in a random zigzag fashion because they are being hit by invisible air molecules. This movement is known as "Brownian motion."

The gradual missing of two or more separate gases or liquids is called diffusion. This mixing is caused by molecules of separate substances colliding and intermingling. This is why you can smell perfumes (whose molecules diffuse through the air) from some distance away.

So to sass the kid's question: Is water liquid or solid? Many substances can exist in more than one state. It is liquid when it flows freely and solid in the form of ice - until the turn again.

Now, tell me about the Snowman.
