DScale accumulates at position "E".
AI Explanation
The correct answer is B) The feed water enters the device and vaporizes under vacuum conditions. In the illustration MO-0110, the space labeled "G" is the boiling chamber where the feed water enters and vaporizes under vacuum conditions. This is a key step in the operation of this type of steam-powered device, as the vacuum helps lower the boiling point of the water, allowing it to vaporize more efficiently. The other answer choices are incorrect because: A) refers to the jacket water rather than the feed water, C) describes cooling the feed water before it enters the device, and D) is about scale accumulation in a different part of the device.
