Liquid Helium
Liquid helium, colder than liquid nitrogen, has also been used for cooling. Liquid helium evaporates at -269 °C, and temperatures ranging from -230 to -240 °C have been measured from the heatsink. However, liquid helium is more expensive and more difficult to store and use than liquid nitrogen. Also, extremely low temperatures can cause integrated circuits to stop functioning. Silicon-based semiconductors, for example, will freeze out at around -233 °C.

Famous quotes containing the word liquid:
““Awake,
My fairest, my espoused, my latest found,
Heaven’s last best gift, my ever new delight,
Awake, the morning shines, and the fresh field
Calls us: we lose the prime, to mark how spring
Our tended plants, how blows the citron grove,
What drops the myrrh and what the balmy reed,
How nature paints her colors, how the bee
Sits on the bloom extracting liquid sweet.””
—John Milton (1608–1674)
