A spilled puddle of juice on a kitchen floor is dry-blown by an electric fan. Which statement explains the effect of the moving air on the rate of evaporation of the liquid?
The moving air transfers thermal energy to the liquid molecules and so increases the rate of evaporation.
The moving air removes evaporated vapor from near the liquid's surface and so decreases the rate of evaporation.
The moving air removes evaporated vapor from near the liquid's surface and so increases the rate of evaporation.
The moving air increases the pressure at the liquid's surface and so decreases the rate of evaporation.
