    The answers are dissolving sugar in water and ice melting. An endothermic process absorbs heat like dissolving sugar in water since the reaction requires energy. Likewise, ice melting is an endothermic reaction since ice molecules are absorbing the thermal energy of the surrounding, moving faster and farther away from each other, changing from a solid state ice to a liquid state water, and therefore energy is being absorbed.
