Chemistry

Chemical energetics is a branch of chemistry that studies the energy changes that accompany chemical reactions and transformations. It involves understanding how energy is absorbed or released during these processes. The fundamental concept in chemical energetics is the notion of energy being conserved, meaning it cannot be created or destroyed but only transferred between systems. There are two main types of energy changes associated with chemical reactions: Endothermic Reactions: These are reactions that absorb energy from their surroundings. Examples in real life include: Photosynthesis: The process by which plants convert light energy into chemical energy in the form of glucose. This reaction absorbs energy from sunlight. Cooking an egg: The process of cooking an egg requires the absorption of heat energy, causing the egg to undergo various chemical changes. Exothermic Reactions: These are reactions that release energy to their surroundings. Examples in real life include: Combustio...
