Question

TB3 Liquid nitrogen is much cheaper than liquid helium. The molecular weight of diatomic nitrogen (N2) is about 28 g/mole and that of atomic helium is about 4 g/mole. One reason for this is that while nitrogen is the most common constituent of the atmosphere, only minute amounts of helium are found in the atmosphere. (Helium is found in natural gas deposits.) Why are only minute amounts of helium found in the atmosphere? TB3 If the absolute temperature of a gas is doubled, what is the change in the rms speed of its molecules? TB3 At what temperature is the Fahrenheit temperature reading twice the Celsius temperature reading?
