How much energy is released, when a drop of water changes its shape from a cube...
How much energy is released, when a drop of water changes its shape from a cube to a sphere of the same volume? Derive a formula.
How much is the drop getting warmer as a consequence of it? Draw a log-lin-graph for drops between 10nm and 10 cm in size. (the log is on the x-axis, the lin on the y axis).
