endotermt

Endotermt is a term used to describe a chemical reaction or process that absorbs energy from its surroundings, typically in the form of heat. This means that the temperature of the surroundings decreases during an endotermic process. In contrast, exothermic processes release energy into their surroundings.

Endotermic reactions require a net input of energy to proceed. This energy is often supplied as heat, light, or electrical energy. For example, photosynthesis in plants is an endotermic process where light energy is absorbed to convert carbon dioxide and water into glucose and oxygen. Another common example is the melting of ice, which absorbs heat from the environment to transform from a solid to a liquid state.

The enthalpy change for an endotermic process is positive, meaning that the products of the reaction have a higher enthalpy (a measure of the total energy of a thermodynamic system) than the reactants. This energy difference is the amount of energy absorbed from the surroundings. Understanding endotermic processes is crucial in various fields, including chemistry, biology, and engineering, for controlling reactions, designing energy-efficient systems, and understanding natural phenomena.
