Answer
The normal boiling point is about 30 Kelvin.
Work Step by Step
Boiling point means the point at which a liquid becomes a gas. Because it is normal boiling point, this means that we are looking at a boiling point in standard conditions, meaning that we consider the boiling point at a pressure of one atmosphere. Looking at the diagram, we see that when pressure is one atmosphere, Neon changes from liquid to gas (the color of the area of the graph changes from blue to yellow) at 30 Kelvin.
