The Quest for Extreme Cold: Liquefaction of Gases Quiz

Faraday achieved the first successful liquefaction of a gas in 1823, liquefying chlorine.

Nitrous oxide, commonly known as laughing gas, was one of the earliest gases to be liquefied.

The primary purpose of liquefying gases is to decrease their volume for easier storage and transportation.

Oxygen liquefies at -195.79°C under standard atmospheric pressure.

Nitrogen was the first gas to be liquefied by Berthollet in 1823.

Adiabatic cooling is used in the liquefaction of gases to lower their temperature.

Critical temperature is the maximum temperature at which a substance can exist in the liquid state, independent of pressure.

Sir James Dewar discovered helium and was the first to liquefy it in 1908.

Helium is the most difficult gas to liquefy due to its low boiling point and weak intermolecular forces.

Cryogenic distillation is the primary technique used in modern gas liquefaction.

Hydrogen was the last of the common gases to be liquefied at atmospheric pressure.

James Prescott Joule developed the Joule-Thomson effect, crucial in gas liquefaction processes.

Carbon dioxide exhibits unusual behavior near its critical point, making its liquefaction challenging.
