Question

For Aysegul:
What if temperature as defined by T=a.(mw).(v^2) was not dependent on the molecular weight of the gas, speculate on how the composition of the earth's atmosphere might have evolved differently since it was first formed?
please help me

Answer 1

If molecular weight, m_w, is out of the picture, then that would mean at the same temperature, gases of lower mass, such as hydrogen, would have much higher velocities, meaning more of them would escape the atmosphere.

So think about what gases would remain in the atmosphere relative to others. In particular, what might have happened at the time of the great oxygenation event?

Answer 2

Could you tell me what a is in that formula?

Answer 3

just a constant

Answer 4

I dont get you. If temperature is independent of the molecular weight, then it should depend on only the velocity(assuming a is a constant), according to that formula. So, at the same temperature, all gases would have same velocity!
