24. 19. Joe spilled half of his cup of water on the classroom floor. The other half was still in the cup. When he came back hours later, all of the water on the floor had evaporated, but most of the water in the cup was still there. (Joe knew that no one had wiped up the water on the floor). Why did the water that spilled on the floor evaporate but most of the water in the glass had not? The water on the floor had a much larger ___________________ ____________________ (area exposed to the ________) than the water in the cup. surface area air
