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
1 answer
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.
