TAKE A UTENSIL WITH A OPEN OR WIDE OPENING.AND A CONTAINER WITH SMALL OPENING.FILL THEM WITH EQUAL AMOUNT OF WATER. AFTER SOME DAYS CHECK THE LEVEL OF WATER PRESENT IN BOTH THE CONTAINER . WE CAN FIND THAT WATER EVAPORATED AT MUCH HIGHER RATE IN THE CONTAINER WITH WIDER MOUTH , AS MORE SURFACE OF WATER COULD COME IN CONTACT TO THE AIR AND EVAPORATE.
