Which component is in the cold section but not in the hot section?

• A. Diffuser
• B. Combustion
• C. Inlet
• D. Turbine

Answer: (C)

Inlet sits at the front of the engine and is part of the cold section, which includes everything before combustion. Its job is to capture ambient air and guide it smoothly into the compressor without being exposed to high temperatures. The hot section contains the combustion chamber and the turbine, where air and fuel burn and hot gases flow, so those components aren’t in the cold section. Since the inlet is located before any combustion and remains at ambient temperature, it is the component that belongs to the cold section but not to the hot section.
