A substance is dissolved in water, and the temperature of the surroundings decreases. Is this process exothermic or endothermic? Explain your reasoning in 3-5 sentences explain
1 answer
This process is endothermic. When a substance is dissolved in water, it requires energy to break the bonds between the particles of the substance and allow them to mix with the water molecules. The energy required is obtained from the surroundings, leading to a decrease in the temperature of the surroundings. Therefore, the overall process of dissolving the substance in water is endothermic, as energy is absorbed from the surroundings.
