Hot pack endothermic or exothermic
WebApr 12, 2024 · Exothermic means the enthalpy of a system decreases ( Δ H < 0) and endothermic means it increases ( Δ H > 0 ). If you choose your system as just the water, the process is endothermic. This makes sense because you are increasing the thermal energy of the water, and if nothing else changes in the system, the energy has to come … WebAn endothermic reaction reduces the swelling by cooling get injury. Educational Resources: Once you hurt is ankle, thermodynamics can help you heal! An endeothermy reaction reduces aforementioned swelling by cooling your injury.

WebHence, the enthalpy change is declining (ΔH<0). By examining this enthalpy change, one can tell whether an reaction is endo (ΔH>0) or exothermic (ΔH<0). The criteria by terms of temperature and the impact on the environment for exothermic and endothermic reactions are as follows: An exothermic reaction releases heats and warms that environment.
