The statement that would best support the student's claim that the type of energy transformation in a hydroelectric dam system is mechanical to electrical is:
**The turbine must turn for electricity to flow from the generator to the power lines.**
This statement highlights the mechanical aspect of the energy transformation, where the kinetic energy from the flowing water turns the turbine (mechanical energy), which then generates electrical energy through the generator.
**The turbine must turn for electricity to flow from the generator to the power lines.**
This statement highlights the mechanical aspect of the energy transformation, where the kinetic energy from the flowing water turns the turbine (mechanical energy), which then generates electrical energy through the generator.
