Greatest efficiency at that temperature.
The lowest temperature at which superconductivity can occur is called the critical temperature. This temperature varies depending on the material. Some superconductors have critical temperatures close to absolute zero (0 Kelvin), while others have critical temperatures as high as -140 degrees Celsius.
Close to Critical has 190 pages.
Close to Critical was created in 1964-07.
Close means nearby. Critical is vitally important.

Ammonia gas can be easily liquefied due to its relatively low critical temperature and pressure. In contrast, helium has a critical temperature and pressure that are very close to absolute zero, making it difficult to liquefy at standard temperatures and pressures.
Stop Boiler Valve (or Crown Valve) is installed on an outlet line of a boiler. It's purpose is isolation of a boiler from a downstream steam line. Its position may be either open or close, it cannot be used for throttling of steam.
To light a boiler safely and effectively, follow these steps: Ensure the boiler is turned off and cool before starting. Check for any gas leaks or unusual smells before proceeding. Open the boiler's access panel and locate the pilot light. Use a long lighter or match to ignite the pilot light, following the manufacturer's instructions. Once the pilot light is lit, carefully close the access panel. Turn on the boiler and adjust the temperature as needed. Monitor the boiler for any unusual sounds or smells, and contact a professional if any issues arise.
0oK, or absolute zero is the lowest temperature. Superconductors have a critical temperature at which they begin to work, but it is the highest temperature, and they function as superconductors at any temperature lower, down to as close to absolute zero as they can be made to be (absolute zero is unachievable).
Those are thermoswitches. They open and close with engine temperature controlling vacuum operated devices such as the EGR and the ignition spark advance.
