Calculate the temperature at which a fog with droplet 300 nm in diameter will evaporate. What should be the droplet size of a fog that would disappear at room temperature(celcius degree)? Assume that the interfacial tension of water remains constant at 72 mN/m. The enthalpy of evaporation of water is 42 kJ/mol.
