Answer by: nisha sheikh
nisha sheikh The surface tension of oil is more than that of hor soup. Due to it, an oil drop does not spread over the hot soup. When the temperature of the soup falls, the surface tension of oil becomes less than that of soup. Due to it, the oil drop starts spreading on the soup.
