Temperature and Average kinetic energy of moleces

[JakeHaji]

1. The temperature of air wil ... if we add a hydrogen molecule of a speed higher than 1980 m s/-1.
2. The temperature of air will ... if we take away a hydrogen molecule of a speed highr than 1980 m s /-1.
3. The temperature of air will ... if we take away a hydrogen molecule of a speed lower than 1980 m s /-1.
4. The temperature of air will ... if we add a hydrogen molecule of a speed lower than 1980 m s/-1.

Is the assumption here that the average speed of all the molecules is 1980 m s/-1? Because if it is not, the answers could be anyone's guess.

Also, what do you think the answer should be?
