WebFeb 18, 2016 · When you put ice (a lot) in water, the water temperature will remain 0°C as long as there is still ice (roughly) and the same stands for the dry ice/acetone; as long as there is some dry ice left, the temperature will remain -78°C. That is why the -78°C is so popular among chemists for low temperature experiments. Share Improve this answer … 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 ...
