Define and explain sublimation and name the substance that sublime directly on heating​

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... So, all solids that possess an appreciable vapour pressure at a certain temperature usually can sublime in air (e.g. water ice just below 0 °C).

I hope it's helpful!

Explanation:

ssf sublimation is when the trasition of a substance directly from the solid to the gas waste without directy passing through the liquid state so that all solids that possess an appreciable vapour pressure at a certain temperature usually can sublime in air
