Which of the Following Gases has Highest Value of Critical Temperature?

Answer –  CO₂ gas has the highest value of critical temperature among given gases.

Carbon Dioxide, (CO₂), a colourless gas having a faint sharp odour and a sour taste. It is one of the most important greenhouse gases linked to global warming, but it is a minor component of Earth’s atmosphere (about 3 volumes in 10,000), formed in the combustion of carbon-containing materials, fermentation, and in respiration of animals and employed by plants in the photosynthesis of carbohydrates. Carbon dioxide was recognized as a gas different from others early in the 17th century by a Belgian chemist, Jan Baptista van Helmont, who observed it as a product of both fermentation and combustion. It liquefies upon compression to 75 kg per square centimetre (1,071 pounds per square inch) at 31 °C (87.4 °F) or to 16–24 kg per sq cm (230–345 lb per sq in.) at −23 to −12 °C (−10 to 10 °F). By the mid-20th century, most carbon dioxide was sold as a liquid.

Summary:

Which of the Following Gases has Highest Value of Critical Temperature?

CO₂ gas has the highest value of critical temperature among given gases. Supervolcano study finds CO2 emissions key to avoiding climate disasters.CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of haemoglobin for oxygen (O2). Fluctuations in CO2 levels are highly regulated and can cause disturbances in the human body if normal levels are not maintained.
