WebThermal conductivity of argon at room temperature (300 K) is 17.72 mW m-1 K-1 (milliWatts per metre per degree) whereas for air it is 26 mW m-1 K-1. For the same reason argon is used to inflate diving suits. Old documents and other things that are susceptible to oxidation can be protected by being stored in an atmosphere of argon. WebBecause helium is less dense than air, helium-filled balloons “float” at the end of a tethering string. Because helium has a molar mass of 4.00 g/mol, whereas air has an average molar mass of about 29 g/mol, pure helium effuses through the microscopic pores in the rubber balloon √294.00=2.7 times faster than air. ordering sandwiches from costco
