Read the following information and answer the questions based on information and related studied concepts. According to Ayushi, when solid X is put into water, it dissolves with evolution of heat and causes a small explosion to produce the two products Y and Z. The characteristics of Y and Z products differ significantly from those of solid X and water. Furthermore, solid X and water cannot be transformed back into products Y and Z. When another solid P is dissolved in water, it absorbs a small amount of heat and forms the product Q, which cools down. The qualities of both solid P and water are represented by the product Q. Product Q can also be turned into solid P and water.
