Dissolving ammonium nitrate in water absorbs heat, making it an endothermic process.

Which of the following is an example of an endothermic process? (2021)

Which of the following is an example of an endothermic process? (2021)

Step 1: Understand what an endothermic process is. An endothermic process is one that absorbs heat from its surroundings.
Step 2: Identify the example given in the question, which is dissolving ammonium nitrate in water.
Step 3: Recognize that when ammonium nitrate dissolves in water, it takes in heat from the water, causing the temperature of the solution to drop.
Step 4: Conclude that since this process absorbs heat, it is indeed an endothermic process.
