This scatter plot maps each element by its melting point (x-axis) versus boiling point (y-axis). The distance from the diagonal line indicates how wide each element's liquid temperature range is.

Elements far above the diagonal have exceptionally wide liquid ranges - useful for applications like liquid metal coolants. Gallium is notable for melting near room temperature but boiling at over 2,400°C, giving it the widest liquid range of any element. This property affects applications from thermometers (mercury) to nuclear reactor coolants (sodium).
