Materials, such as water, that becomes gaseous easily at room temperature are called volatiles. How does the complete lack of volatiles in lunar rocks support the impact theory of the moon’s formation?

The lack of volatiles in lunar rocks supports the impact theory of the moon's formation because it suggests that the formation of the moon was caused by a large object striking the Earth, since the force of the impact would have unleashed an immense amount of energy that would be sufficient to vaporize the surrounding volatiles. In other words, the impact could have caused all of the volatiles in the area to evaporate and be expelled from the moon, leaving it virtually devoid of them. Thus, the lack of volatiles in lunar rocks provides further evidence for the impact theory of the moon's formation.
