Witryna14 mar 2024 · A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from … In thermochemistry, an endothermic process (from Greek ἔνδον (endon) 'within', and θερμ- (therm) 'hot, warm') is any thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. Thus, an endothermic reaction generally leads to an increase in the temperature of the system and a decrease in that of the surroundings. It ma…
