Determine the heat absorbed

WebJun 18, 2024 · If heat is absorbed or enters the system, the process is endothermic and if heat is evolved or exits the system, the process is exothermic. In the laboratory, heat flow is measured in an apparatus called a calorimeter. A calorimeter is a device used to determine heat flow during a chemical or physical change. WebDetermine the change in temperature. ΔT = T f − T i. Graph the change in temperature of chemical salt compared to the mass of chemical salt. Draw a best fit line for the points. Optional data analysis: Calculate the heat …
