Question

Solid substances are most likely to sublime if they have...?

Answer 1

Answer:

a. High vapor pressures

b. Weak intermolecular forces

Explanation:

a. Sublimation occurs when the vapor pressures is equal to the applied pressure in the solid. Therefore, the higher the vapor pressure, the easier it is to be equal to the external pressure and the most likely is the solid to sublime.

b. Sublimation requires intermolecular forces to be weakened in order to go from the solid state to the gas state. Therefore, the weaker the intermolecular forces, the easier sublimation will be.

Answer 2

Technically the are both right and wrong. Solid substances are most likely to sublime is they have... high vapor pressure and weak intermolecular forces.
