Is it possible that water evaporates from a spherical drop of water just by means of surface energy supplying the necessary latent heat of vaporisation? The drop does not use its internal thermal energy and does not receive any heat from outside. It is known that water drops of size less than `10^(�6)` m do not exist. Latent heat of vaporisation of water is `L = 2.3 � 10^(6) Jkg^(�1)` and surface tension is `T = 0.07 Nm^(�1)`.
