Why is hot soup tastier than cold one?

Answer 1

Answer:We know that the surface tension of a liquid decreases with the increase in temperature. So, the surface tension of hot soup is less than that of cold one and hence hot soup spreads over a larger area of the tongue of a person. That makes hot soup more tasty than the cold one.It is the reason why hot soup is tastier than cold one.
