A substance is dissolved in water, and the temperature of the surroundings decreases. Is this process exothermic or endothermic? Explain in 3 to 5 sentences

1 answer

The process of dissolving a substance in water is generally an exothermic process, meaning it releases energy in the form of heat. When a substance dissolves in water, water molecules surround the solute particles, causing them to break apart and form new bonds with the water molecules. This process releases energy as the new solute-water bonds are formed. Therefore, as the temperature of the surroundings decreases during the process, it can be concluded that dissolving the substance in water is an exothermic process.
