It is believed that water must be present for life to exist. The moon has no atmosphere and the surface temperature ranges from 100 degrees C during the day to -175 C at night. If water exists on the moon, it must exist as a solid or liquid. Water in its gas state on the moon would float away into space since the moon has no atmosphere, Based on these conditions and the phase diagram of water, predict whether water exists on the moon. Give reasons, Include in your answer a statement about the atmospheric pressure on the moon. Draw the phase diagram of water and put a on the phase diagram to show the pressure and temperature conditions in the day and at night on the moon.
