Question

Do all sublimable substances 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
