Explain in 4 sentences: A substance is dissolved in water, and the temperature of the surroundings decreases. Is this process exothermic or endothermic? Explain your reasoning
This process is endothermic. When a substance dissolves in water, energy is required to break the bonds between the particles of the substance. This energy is absorbed from the surroundings, causing the decrease in temperature. The fact that the temperature of the surroundings decreases indicates that the process is endothermic.
When a substance dissolves in water and the temperature of the surroundings decreases, the process is usually considered to be endothermic. This is because energy is required to break the bonds between the solute particles and allow them to mix with the water molecules. As a result, the energy is absorbed from the surroundings, leading to a decrease in temperature. Therefore, an endothermic process is occurring in this scenario.
