HEAT OF SOLUTION

"When sodium hydroxide is dissolved in water, a large amount of heat is released, indicating a highly exothermic heat of solution."

"The heat of solution for potassium chloride in water is considered endothermic, as it absorbs heat from the surroundings."

"The heat of solution for ammonium nitrate is highly endothermic, causing a significant decrease in temperature when dissolved in water."

"The heat of solution of calcium chloride in water is exothermic, resulting in a temperature increase of the solution."

"The heat of solution for sugar in water is relatively low, as it does not require or release a significant amount of heat during dissolution."
