To calculate the difference in temperature between the water at the top and bottom of Niagara Falls, we can follow these steps: ### Step 1: Understand the Energy Conversion When water falls from a height, its potential energy is converted into kinetic energy. If we assume that all the kinetic energy is converted into heat energy, we can use this relationship to find the change in temperature. ### Step 2: Write the Formula The potential energy (PE) of the water at the top can be expressed as: \[ PE = mgh \] ...
