Evaporation happens when high-energy molecules in a liquid escape from the liquid’s surface and get converted into vapours. As particles with greater energy keep on leaving the liquid as time goes on, the liquid’s temperature keeps on dropping as well. Which of the following properties of the liquid do you think will lead to an increase in the rate of evaporation? 


Increasing the temperature will provide more and more such high-energy particles wanting to escape (evaporation is increased), increasing the surface area will provide a greater space for these high-energy particles to escape from (evaporation is increased) while strong inter-molecular forces will keep the particles held together strongly, preventing high-energy molecules from escaping too much (evaporation is decreased).
