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.

A Solid substances will like undergo sublimation under these conditions;

a) high or low vapor pressures.

b. weak or strong intermoleculer forces.

  • Sublimation can be regarded as the  conversion of solid to the gaseous phases of matter, without passing through the intermediate liquid stage.

  • Occurrence of Sublimation usually take place when there is the magnitude of the vapor pressures  and the applied pressure in the solid is equal.

  • When there is higher vapor pressure, it will be very easy for the solid to have high external pressure which will result to higher tendency to sublime.

  • For Sublimation to occur, the intermolecular forces within the solids must be  weakened so that it will be easier for the molecules of the solid to move to  the gas state.

Therefore, Sublimation usually take place as a result of vapor pressures having  the magnitude with applied pressure in the solid.
