Henry Cavendish, while investigating atmospheric nitrogen (“phlogisticated air”), had concluded in 1785 that not more than 1/120 part of the nitrogen might be some inert constituent. The story of its discovery started when Rayleigh found that the nitrogen extracted from the air had a higher density than that made by decomposing ammonia. Thermal conductivity of argon at room temperature (300 K) is 17.72 mW m. The most exotic use of argon is in the tyres of luxury cars.
