What is the temperature at which the substance can be both in the solid and the liquid phase?

Gas–liquid–solid triple point

The single combination of pressure and temperature at which liquid water, solid ice, and water vapor can coexist in a stable equilibrium occurs at approximately 273.1575 K (0.0075 °C; 32.0135 °F) and a partial vapor pressure of 611.657 pascals (6.11657 mbar; 0.00603659 atm).

Explanation:

It represents the equilibrium between the liquid and gas phases. The point on this curve where the vapor pressure is 1 atm is the normal boiling point of the substance. The vapor-pressure curve ends at the critical point (B), which is at the critical temperature and critical pressure of the substance.

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
