During what phase of the steam cycle does water convert from a liquid to a vapor?

• A. Generation Stage
• B. Condensation Stage
• C. Superheating Stage
• D. Feedwater Stage

Answer: (A)

In the steam cycle, the phase in which water converts from a liquid to a vapor is known as the Generation Stage. This stage involves the heating of water in a boiler where it reaches its boiling point and begins to vaporize. The energy added to the water during this stage primarily comes from the combustion of fuel, which increases the temperature and pressure of the water until it transforms into steam. In contrast, the other stages mentioned involve different processes. During the Condensation Stage, steam cools and releases heat, transitioning back into a liquid state. The Superheating Stage occurs after the water has already turned into steam and involves further heating of the steam to increase its temperature and energy before it is used for work. The Feedwater Stage refers to the introduction of water back into the system to replenish the supply after steam has been used, and it does not involve the phase change between liquid and vapor directly.
