Question

explain whether the statement is true or false:-sublimation is occures only when the solid is heated?

Answer 1

false...
 because sublimation occurs when a substance attains its boiling point...

Answer 2

No it's false coz sublimation doesn't occur if only the solid is heated.sublimation means changing into solid to vapour without changing into the liquid.so its not only possible by heating as we can see the camphor- if we keep it outside for some time we can observe that the camphor will be no more in solid state it changes into vapour.and this is also possible by heating.but if naphthalene balls are keep outside they directly change into vapour so does solid carbon dioxide. So sublimation doesn't only have to occur when a particular substance is heated. Hope this helps.pls mark as brainliest....
