What Are Three Everyday Exothermic Reactions You Should Know About?

Exothermic reactions are processes in which energy is released from a system into its surrounding environment, typically in the form of heat, although it can also manifest as electricity, light, or sound. These reactions are commonplace in our daily lives, and here are three illustrative examples:

1. Combustion of Fuel: One prevalent exothermic reaction is the combustion of fuels such as gasoline or natural gas in vehicles and stoves. During this process, chemical bonds within the fuel molecules break, releasing energy in the form of heat and light. This heat is harnessed for various applications, from powering engines to cooking food.

2. Baking Bread: Baking bread involves an exothermic chemical reaction when the dough is placed in an oven. As the dough heats up, the yeast in it undergoes fermentation, releasing heat energy. This not only bakes the bread but also imparts its delicious aroma and taste.

3. Respiration: Within our bodies, the process of respiration is an exothermic

Exothermic reactions release heat energy as they occur. Here are

What are some common examples of everyday exothermic reactions? Exothermic reactions release energy in the form of heat, and they are widely observed in various applications. For instance, self-heating cans, which utilize exothermic reactions, are designed to warm their contents when needed. Additionally, hand warmers are another practical example of exothermic reactions in action. In contrast to exothermic reactions, endothermic reactions absorb energy from their surroundings, causing a decrease in the surrounding temperature.

• combustion (burning)
• neutralisation reactions between acids and alkalis.
• the reaction between water and calcium oxide.

• Melting ice cubes.
• Melting solid salts.
• Evaporating liquid water.
• Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.
