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 simply
This process is endothermic. When a substance is dissolved in water, energy is required to break the bonds between the particles of the substance. This energy is absorbed from the surroundings, causing the temperature of the surroundings to decrease. In an exothermic process, the temperature of the surroundings would increase as energy is released, but in this case, the temperature decreases, indicating that energy is being absorbed, making it endothermic.
simpler terms
This process is endothermic because it absorbs energy from the surroundings, causing the temperature to drop.
