Answer:
Explanation:
In evaporation a substance changes its state from liquid to gas, for this process to occur energy in the form of heat is required (endothermic process) which has to be taken from some source (surroundings). So the source, which loses heat apparently becomes 'cooler'. Hence it can be said that evaporation causes cooling.
