Always endothermic. Liquids absorb heat from the surroundings through evaporation, and keeps continuing this to regain lost energy. This produces a cooling effect in the surroundings.
Endothermic and exothermic reactions are chemical reactions where as cooling a beer is simply moving heat from one place to another. So to answer your question, cooling a beer is neither endothermic, nor exothermic, it is thermally neutral. That is to say that ( not counting heat generated by inefficiency ) the amount of heat remains constant throughout the "cooling" process.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Exothermic/endothermic is a process not a feeling.
endothermic reaction a positive enthalpy.
Acetone draws heat away from an item as it evaporates, so if you put acetone on your nails your nails will feel cold.
Evaporation is an endothermic process, absorb energy.

It is an endothermic process.
Condensation is exothermic reaction because it is the process of conversion of gas into liquid by cooling and for cooling heat is released. Hence, it is exothermic reaction.Hope you are satisfied with the answer.
