    1. The problem statement, all variables and given/known data
    A lightning flash transfers 2.5 C of charge and 3.3 MJ of energy to the Earth.

    (a) Across what potential difference did it travel? 1.32 MV
    (b) How much water could this boil and vaporize, starting from room temperature?

    2. Relevant equations

    need help finding equations for b

    3. The attempt at a solution
