The Essentials of Chemistry Basics

Chemistry is the branch of science that deals with matter, which is anything that has mass and occupies space. You’ll need to get up to speed with some chemistry basics before you explore more complex topics relating to chemical reactions and processes.

How Would You Define Chemistry as a Science?

Chemistry is a branch of science that studies the composition and properties of matter and the changes it undergoes. Chemistry is far more than a collection of facts and a body of knowledge. It’s all about [more…]

The Changing States of Solids, Liquids, and Gases

When a substance goes from one state of matter — solid, liquid, or gas — to another state of matter, the process is a change of state. Some rather interesting things occur during this process. [more…]

How to Distinguish Pure Substances and Mixtures

Chemists can classify matter as solid, liquid, or gas. But there are other ways to classify matter, as well — such as pure substances and mixtures. Classification is one of the basic processes in science [more…]

How Scientists Measure Matter

Scientists are often called on to make measurements of matter, which may include such things as mass (weight), volume, and temperature. A worldwide measurement system has been adopted to ensure that scientists [more…]

The Properties of Chemical Substances

When chemists study chemical substances, they examine two types of properties: chemical properties and physical properties. Some physical properties are [more…]

What Are the Different Types of Energy?

Energy can take several forms — such as heat energy, light energy, electrical energy, and mechanical energy. But two general types of energy are especially important to chemists: kinetic energy and potential [more…]

How Is Energy Measured?

You can measure kinetic energy (energy of motion) with a thermometer. Measuring potential (stored) energy can be a difficult task. The potential energy of a ball stuck up in a tree is related to the mass [more…]

The Periodicity of Chemical Elements

A pattern of repeating order is called periodicity. In the mid-1800s, Dmitri Mendeleev, a Russian chemist, noticed a repeating pattern of chemical properties in elements. [more…]
