When a powder dissolves in water a ​solution​ is formed. The powder is the ​solute​ and the water is thesolvent.​ Oftentimes energy changes accompany the formation of a solution. When added to water, somepowders cause the resulting solution to get hot, while others make it cold. Some powders don’t produce atemperature change at all. When energy changes do occur, they can be put to good use.Introduction:​ The reactions in this activity are performed within a ​calorimeter​, an in...
