Endothermic just means that heat has to be supplied to the proces to keep it going. It can be fysical or chemical.


Examples of physical endothermic processes:
The melting of ice, the evaporation of water.

Examples of chemical endothermic processes:
The electrolysis of water #2H_2O->2H_2+O_2#
The 'burning' of limestone to get quicklime: #CaCO_3->CaO+CO_2#
