Answer:
The constant density decreases
Explanation:
As the temperature of a solvent increases, the solubility of any gas dissolved in that solvent decreases.
For example:
when the temperature of a river, lake or stream is raised high , due to discharge of hot water from some industrial process the solubility of the oxygen in the water is decreased .The fish and the other organisms that live in the water bodies such as rivers, ponds, lakes etc can survive only in the presence of oxygen and decrease in the concentration of the water due to increased temperature can lead to the death of the fish and this may in turn damage the ecosystem.
In the above example, water is considered as the solvent and the oxygen is considered as the solute. When the temperature of the solvent that is water increases, the solubility of the gas that is oxygen in the solvent decreases.
Therefore the answer is decreases

Answer:
Endothermic reaction
Explanation:
A cold pack is used as a cold compress in order to numb pain caused by minor injuries. it is useful in first aid treatment of bruises, sprains, cuts and burns in addition to the application of a bandage.
A cold pack functions by absorbing heat away from the surrounding thereby decreasing the temperature and making the surface to feel cool. This is an endothermic reaction.
In an endothermic reaction, heat is absorbed from the environment and the reaction surface feels cool. Hence, an endothermic reaction is most useful in making a cold pack because the product of the endothermic reaction will feel cool to touch making it suitable to be used as a cold pack in first aid.
