In a mixture of Hydrogen and Oxygen at the same tempreture, which molecules moves faster?

Answer 1

Hydrogen because it has less mass. its really simple.
tempreture is the same so the energy is the same. thus the lighter one is moving faster.

Answer 2

According to the Kinetic Theory of Gasses The Hydrogen molecules will be moving about 4 times as fast as the Oxygen molecules at the same temperature.

Answer 3

temperature is a measure of kinetic energy...since both molecules have the same kinetic energy, the lighter one must be moving faster, hence Hydrogen is moving faster than oxygen
