1. The problem statement, all variables and given/known data The question states: You notice a thuderstorm and calculate the Potential Difference between a cloud and a tree to be 150 MV. You know that a lightning bolt delivers 60 C of charge. If the tree only absorbs 5% of the energy of this lightning bolt, with the rest going to the ground, if they tree is at 30 degrees C, how much water can be boiled away within the tree? Water has a specific heat of 4186 K/Kg degrees C, and boiling point is 100 degrees C, heat of vaporization is 2.26 x 10^6 J/Kg 2. Relevant equations V = PE/q Q=MC delta T Q = ML There must be something with Density, but I'm not completely sure. 3. The attempt at a solution I figured out using V = PE/q (Solving for PE) that the Potential Electric Energy is 9 x 10^9, and that 5% of that is 45 x 10^7 (I'm pretty sure that's correct, but if I'm wrong let me know). From there, I'm not all to sure where to go since I'm not given an initial mass or a final temperature. Any help would be greatly appreciated.
