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
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.
When a substance is dissolved in water and the temperature of the surroundings decreases, the process is considered to be endothermic. In an endothermic process, energy is absorbed from the surroundings, which leads to a decrease in temperature. When the substance dissolves in water, it requires energy to break the intermolecular forces between its particles and allow the particles to mix with the water molecules. This energy is taken from the surroundings, resulting in a decrease in temperature. Therefore, the decrease in temperature indicates an endothermic process.
