"WebIn 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. [1] In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. " - Entropy def chemistry
