Question

What is true about the solution process involved in an instant cold pack

Answer 1

Step-by-step explanation:

When ionic substances are dissolved in water, which is referred to as 'heat of solution', heat can be released or absorbed. An instant cold pack, for instance, is made of endothermically dissolving ammonium nitrate in water. A hot pack is produced from exothermically dissolved calcium chloride in water.

Answer 2

Heat can be released or absorbed when ionic substances are dissolved in water, which is referred to as "heat of solution". For example, an instant cold pack is made of ammonium nitrate dissolving endothermically in water. A hot pack is made from calcium chloride dissolves exothermically in water.
