Question

define: do all the sublimable solids, sublime at the same temperature justify your answer

Answer 1

No, all the substances do not sublime at the same temperature.
Reason :
Sublimation is a process where solid directly converts into gas without turning into liquid.
Factors effecting Sublimation :
1. Depends on inter molecular force of attraction between the particles in the solid state.
More the interaction between the particles , lesser is the tendency to sublime.
2. Weight of the substance .
As weight increases , the rate of sublimation increases .
3. Nature of the substances.
Hence as these factors vary for all the substances.
So, all sublimable substances do not sublime at the same temperature

Answer 2

no for example naphthalene balls sublime at different temperature while camphor sublime at different temperature
