Which of the following is NOT a use for steam?

The correct choice identifies steam's limited role in computer chip manufacturing. Steam is primarily employed in various industrial processes for its heat energy, which is crucial in applications like steel manufacturing, where it aids in maintaining high temperatures essential for processes such as smelting. In the context of removing skin from potatoes, steam is also a common method, utilized to loosen the skin for easier peeling.

In contrast, computer chip manufacturing relies on a different set of technologies and processes that do not typically utilize steam. Instead, it requires precise environments and conditions involving cleanroom protocols, photolithography, and chemical etching processes, none of which commonly involve steam. This distinguishes computer chip manufacturing from the other processes mentioned, justifying why it is not a typical use for steam.
