Jim
i)Pressure deficit: rate of evaporation is proportional to the difference between the vapor pressure at the surface and the vapor pressure of the overlying air.
ii)Turbulence caused by wind and thermal convection – transports the vapor from the surface layer, allowing evaporation to continue.
iii)Heat supply – gives energy for evaporation to occur.
iv)Conditions at the surface – e.g. dissolved salts reduce vapor pressure of a water surface affects rate of evaporation independently.
