Question

Is intermolecular force in solid , which undergo sublimation ,more or comparatively less ? give reasone?

Answer 1

Answer:

Intermolecular Forces. Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. ... The attractive intermolecular forces between particles that tend to draw the particles together.

A few typical solids undergo sublimation at low pressures (under vacuum). At standard, atmospheric pressure, a few solids which will sublime are iodine (at slightly higher than room temperature), carbon dioxide (dry ice) at -78.5 degrees Celsius, as well as naphthalene (used in mothballs) and arsenic.

Then it's called sublimation. ... Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram.

Those substances that dont have liquid phase due to sublimation. This happens because the vapour pressure of some substances is higher when in the solid form than the liquid form. ... Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.
