Why making bonds is exothermic? When bonds are formed the system loses energy and hence increases its stability (which is the ultimate motive). Since their is a decrease in energy, the energy lost is released as heat energy and thus it is an exothermic process. Is the formation of molecules endothermic or exothermic? The opposite […]

What happens when two objects have the same temperature?
What happens when two objects have the same temperature? When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects. Why do objects heat up at different rates? Higher the temperature difference, […]
