Chemical processes are the series of steps that involve the transformation of substances through chemical reactions. These reactions occur when atoms rearrange to form new compounds, often resulting in changes in properties such as color, temperature, or state. Common examples include combustion, where a substance reacts with oxygen to produce heat and light, and photosynthesis, where plants convert sunlight into energy. In everyday life, chemical processes are essential for various applications, from cooking to manufacturing. For instance, when baking, baking soda reacts with acid to produce carbon dioxide, causing dough to rise. Understanding these processes helps us appreciate the science behind many natural and artificial phenomena.
