A certain storm cloud has a potential difference of 1.50 108 Vrelative to a tree. If, during a lightning storm, 60.0 C of chargeis transferred through this potential difference and 1.00% of theenergy is absorbed by the tree, how much water (sap in the tree)initially at 35.0°C can be boiled away? Water has a specific heatof 4186 J/kg·°C, a boiling point of 100°C, and a heat ofvaporization of 2.26 106 J/kg.
