Chemistry Experiments archive is ordered in this category. Chemistry is the study of matter and energy and the interactions between them. It is a physical science that is closely related to physics, which often shares the same definition.

Chemicals are not just those substances in laboratories or something that is not a natural substance. Far from it, chemists believe that everything is made of chemicals. Everything you hear, see, smell, taste, and touch involves chemistry and chemicals. And hearings, seeing, tasting, and touching all involve intricate series of chemical reactions and interactions in your body. With such an enormous range of topics, it is essential to know something about chemistry. If you want to understand the world around us, you have to do some chemistry experiments.

In more formal terms chemistry is the study of matter and the changes it can undergo. Chemists sometimes refer to matter as ‘stuff’, and indeed so it is. Matter is anything that has mass and occupies space. Which is to say, anything you can touch or hold. Nevertheless, all matter is composed of various combinations of these basic elements. The beauty of chemistry is that when these basic particles are combined, they make something new and unique. Consider the element sodium. It is a soft, silvery metal. It reacts violently with water. When it reacts, it gives off hydrogen gas and enough heat to make the hydrogen explode.

The weight you lose as a result of working out is lost as CO2 and H2O vapour. Obvious in a way, but still impressive when you consider the sheer mass of that gas.
