This is a question that has been debated for centuries.
The answer to this question is not an easy one, as there are many variables at play.
However, in this blog post we will explore the factors that contribute to the pressures needed for solid sulfur to sublime and what happens when it does.
The first factor that contributes to the pressure needed for solid sulfur to sublime is its melting point.
In this case, a high melting points translates into more energy being required in order for it to melt.
And become liquid sulfur while low temperatures often mean lower pressures are needed.
It has been found that at room temperature or below.

Most solids will provide enough heat from their surroundings .
Such as sunlight so they don’t need other methods of heating up like an oven or flame.
Another important contributor to how much pressure is necessary when transforming solids into gases is density .
Higher densities require less gas molecules.
Which means less kinetic energy needs to be applied in order for them to break down into gaseous states.
