if I remember correctly, for ideal gasses, the average kinetic energy is proportional to the absolute temperature

so, 20 degrees C, in absolute (Kelvin scale) is 293 K and 40 degrees C is 313 K

the factor, or ration of the proportionality constants would be equal to 313/293 = 1.07

in other words, 40 C Neon has 1.07 times as much kinetic energy as 20 C Neon

I have slept a lot of times since my beginning chemistry classes but I think that is how it works.
