Did you know?
WebA calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature. When an endothermic reaction occurs, the heat required is absorbed ... WebCalorimetry & Heat Transfer(QB) - Free download as PDF File (.pdf), Text File (.txt) or read online for free.
