Some incandescent light bulbs are filled with argon gas. what is vrms (in m/s) for argon atoms near the filament, assuming their temperature is 2000 k?

The root mean square of the particles in a gas is given by

where
R is the gas constant
T is the absolute temperature of the gas
Mm is the molar mass of the gas

For the argon gas in our problem, the temperature is T=2000 K while the molar mass of argon is , so we can find the rms speed of the gas by using the previous formula:

Aliquid is an answer i hope this

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.
