See complete explanation.
Explanation:
Hello.
In this case since the calorimeter is known as a device designed in order to provide measurements regarding the amount of heat required or transferred during chemical or physical process via the temperature change for the measured mass recorded by the calorimeter. Thus, when exothermic chemical reactions are carried out inside calorimeters the temperature is increased as they release heat whereas endothermic chemical reactions produce a temperature decrease since heat is absorbed.
In such a way, for a burning piece of coal which is releasing heat due to its combustion, we can compute the heat transferred to the water by reasoning that the heat released by the coal is gained by the water so the following relationship can be written:
[tex]Q_{coal}=-Q_{water}[/tex]
Which can be also written by:
[tex]m_{coal}C_{coal}\Delta T_{coal}=-Q_{water}[/tex]
Whereas by knowing the mass, specific heat at constant volume and the temperature change for the coal, we can compute the transferred heat to the water.
Best regards.
Answer:
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 from the thermal energy of the solution, which decreases its temperature. The temperature change, along with the specific heat and mass of the solution, can then be used to calculate the amount of heat involved in either case.
