The turbine nozzle blades convert the combustion gases heat and pressure energy into what form of energy?

Correct Answer: Option D — Velocity

Turbine nozzle blades, or stators, are stationary airfoils that accelerate combustion gases. By constricting the flow path, they convert the high-pressure, high-temperature thermal energy of the gas stream into kinetic energy, or velocity, which is then directed onto the turbine rotor blades to produce mechanical work.
