Will sublimation occur for all substances if the pressure is correct?

Yes it is. Dry ice, or liquid carbon dioxide, is a classic example because it does not go through the liquid phase. The opposite of sublimation is deposition (gas to solid).

Sublimation can occur because solids like liquids have a?
Vapor pressure
What purpose did the vacuum serve during the sublimation purification of caffeine?
it is used because some organic compounds do not sublime at atmospheric pressure so by using the vacuum it substantially reduces the pressure so that they can be purified by sublimation. it also makes decomposition and melting less likely to occur during the sublimation.
What process could make a snowbank colder deposition or sublimation?
Sublimation because sublimation would usually occur on a warm day.
What occur only on the surface of the substance?
sublimation
Does pure substances have a fixed composition?
No. The nobel gases and the rare earth metals (gold, platinum) occur as pure substances in nature because they are relatively unreactive. Most materials do not occur as pure substances (typically oxidized) and must be treated to be made pure.

What turns from a solid to a gas without the solid turning to liquid?
This process is called sublimation and can occur with many solids given the correct conditions of temperature, pressure, and humidity. The famous substance that does this is dry ice or frozen carbon dioxide.

Sublimation because sublimation would usually occur on a warm day.
What occur only on the surface of the substance?
sublimation
How separate the sand and camphor by sublimation process?
Sublimation of camphor occur faster by heating and sand remain.
How does sublimation occur in nature?
Snow and ice can sublime !
Sublimation occurs when?
Sublimation is when a substance turns from a solid to a gas (or the reverse). This can occur when blowing on dry ice or in volcanoes.
Is sublimation absorbing or releasing heat energy?
Sublimation is an endothermic transition from the solid state to the gaseous without passing through the liquid phase so YES, it requires energy. Iodine is one example of a substance that will sublime at normal pressure and so are carbon & arsenic. At a certain temperature and pressure, most substances have what is know as a "triple point". This is where the solid, gas and liquid all occur at the same temperature. It still requires energy to transform one into the other. In other words, if you have a solid, liquid and gas of some substance at the triple point and add energy, some of the solid will become liquid and some of the liquid will become gas but the temperature will remain the same. Substances which sublime at normal pressures (iodine, carbon & arsenic) are at a pressure which is below their triple point. It still requires energy to move from one state to the other.
What planet does sublimation occur naturally on?
Sublimation occurs naturally on Earth. Snow and ice can sublimate slowly in hot sun.
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
