A small water droplet of diameter D = 100 μm and temperature Tmp = 0°C falls on a nonwetting metal surface that is at temperature Ts = −15°C. Determine how long it will take for the droplet to freeze completely. The latent heat of fusion is hsf = 334 kJ/kg. Hint: consider what will be true of the water droplet temperature given its initial temperature.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

because growing process had stoped after 4-5 year
