Why does blowing over hot soup cool the soup?
Step 1 of 3
Solution 5E Hot soup cools mainly by the process of evaporation of water of the soup. The higher the rate of evaporation, faster the soup will cool. Now the rate of evaporation also depends on the concentration of water in just above the soup. When we blow over the soup, the flowing air, removes all the water molecule that is accumulated above the surface of the soup because of the evaporation of the water. This reduces the concentration of the water molecule in the air just above the soup surface and hence increases the rate of the evaporation. Since the rate of evaporation increases, the soup cools down faster.
