A substance is dissolved in water and the Tempe of the surroundings decreases is this prices exothermjc or endothermic
If the temperature of the surroundings decreases, it means that heat is being released from the surroundings. This release of heat indicates an exothermic process. Therefore, when a substance is dissolved in water and the temperature of the surroundings decreases, it is an exothermic process.
Based on the information provided, when a substance is dissolved in water and the temperature of the surroundings decreases, this implies that heat is being released or given off to the surroundings. Therefore, this process is exothermic.
To determine whether the process is exothermic or endothermic, we need to understand the concept of heat transfer.
When a substance dissolves in water and the temperature of the surroundings decreases, it means that heat is being absorbed from the surroundings.
If heat is being absorbed from the surroundings, it implies that the process is endothermic. Endothermic processes require an input of energy, which is usually in the form of heat. In this case, the dissolution of the substance in water is absorbing heat from the surroundings, leading to a decrease in temperature.
Therefore, the scenario described is an example of an endothermic process.
