You have two identical containers, one containing gas A (mA = 6.64 ×10?27 kg) and one containing gas B (mA = 1.39 ×10?27 kg). Both gases are under the same pressure and are at 10.0°C.
(a) Which molecules (A or B) have the greater average translational kinetic energy per molecule?
(b) Now you want to raise the temperature of only one of the containers so that both gasses will have the same rms speed. For which gas should you raise the temperature?
(c) At what temperature will you accomplish your goal?
(d) Once you have accomplished your goal, which molecules (A or B) now have greater average translational kinetic energy per molecule?
It's generally okay to ignore relativistic effects when a particle's speed is less than 1.0% of the speed of light, Find the accelerating potential difference that will bring electrons to that speed, starting from rest
