What is the name of the temperature -273 Degrees C?
Absolute Zero
Where is the coldest place on earth?
South Pole
What processes was used to achieve lower and lower temperatures toward -273
Degrees C?
Using Dewars flask and liquid gasses like oxygen
What happened to the ball in liquid oxygen?
The ball turned hard and broke when hit by the hammer
What did Faraday call the gasses that couldn't be liquefied by pressure?
Permanent gasses
How did Van der Waals propose to liquefy these gasses?
To cool the gasses
Who were the scientists involved in the quest to conquer "Mt. Hydrogen"?
Dewar and Heike
how cold is liquid hydrogen?
-252 degrees C
Who won the assault to "Mt Hydrogen"
Dewar
who had won the race to liquefy helium?
Heike
What was the prize for winning the race to liquefy helium?
Nobel Prize
Who successfully explained superconductivity?
Heike
What is the viscosity of a superfluid
Zero viscosity
What is the central idea behind quantum mechanics?
Atoms are particles
What is a Bose-Einstein condensate?
New form/state of matter; matter can exist at various states; A Bose-Einstein
condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures
very close to absolute zero (that is, very near 0 K or −273.15 °C). Under such
conditions, a large fraction of bosons occupy the lowest quantum state, at which point
macroscopic quantum phenomena become apparent.
what tool did Cornell and Wieman use to cool the metallic atoms?
Lasers (slow down and become cold)
What did Carl Wieman get from the fax machine?
The chip that makes the laser
