Please don't send me the same answer that you have already in Chegg because that answer is wrong.

1. A spherical droplet of water (for example a rain drop, or in a humidification unit) with initial diameter 3 mm is falling through stagnant air. As a result, it is evaporating at a rate that we can assume to be proportional to its surface area. In CBE 120C Mass Transfer, you will learn about the origin of this assumption and where it comes from. But for now, for simplicity, assume that the evaporation rate is given by: Evaporation Rate = 4.44 x (surface area) where the evaporation rate is in g/s, and surface area is in m?. a. Find an expression that predicts the droplet diameter as a function of time. b. How long will it take for the volume of the droplet to be reduced to half of its initial value
