An internal energy of $1029~J$ is produced per kilogram.
The increase in internal energy is equal to the initial gravitational potential energy of the water at a height of 105 meters: $\Delta E = mgh$ $\Delta E = (1.0~kg)(9.80~m/s^2)(105~m)$ $\Delta E = 1029~J$ An internal energy of $1029~J$ is produced per kilogram.
