Question

On heating from low temperature at 1 atm of pressure which substance is most likely to sublime rather than melt?

Answer 1

Since the choices are not given, I can't give an exact answer. Sublimation is the physical change occurring from solid to gas. This is very rare because the molecular arrangement of a solid and gas are opposite to each other. Thus, it depends on the properties of the substance. For example, napthalene could sublime at room temperature.
