A redefinition of the word "sublime".
Gases don't sublime. Solids sublime and turn into gases. When a gas turns into a solid, that's called deposition.
Okay, SOME people use "sublimation" for a gas-solid phase transition no matter which way it goes. These people are wrong. There's no excuse for this kind of shoddy nomenclature, when there is a perfectly good word for the gas-to-solid transition. Two, in fact, you could also use "desublimation".
What else can I help you with?
Does ethanol sublime?
No. Only solids sublime, as sublime means to go from a solid directly to a gas. Ethanol evaporates.
What is needed fora solid to sublime and what change of state occurs?
For a solid to sublime, it needs to undergo a change in temperature and pressure that allows it to transition directly from a solid to a gas without passing through the liquid state. This change of state is called sublimation.
Is urea a sublime substance?
No, urea is not a sublime substance. Sublimation is the process where a solid directly turns into a gas without going through the liquid phase. Urea undergoes decomposition when heated, releasing ammonia gas and leaving behind a residue.
What substance does not sublime?
Glass is a substance that does not sublime. Sublimation is the process where a solid turns directly into a gas, skipping the liquid phase. Since glass is an amorphous solid made up of densely packed atoms, it does not easily transition directly into a gas.
What ice of the comet turns into gas?
All ices on comets sublime to gas as it approaches toe sun.
Do the sublime elements have liquid state?
No, the sublime elements do not have a liquid state. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through a liquid phase. Examples of substances that sublime include dry ice (solid carbon dioxide) and camphor.
What is the common property of iodine and naphthalene?
they both sublime, in which the solid particles will change directly into gas.
Does Mercury sublime?
Yes, Mercury can sublime, or transition directly from a solid to a gas at certain conditions. Because of its low boiling point, Mercury can evaporate at room temperature, creating a vapor that is toxic to humans.
What is needed for a solid sublime and what change of state occurs?
pressure and the change of state is chemical
What temperature does iodine begin to sublime?
Vaporization of iodine occur after 113 oC.
What is the process of a solid turning into a gas is called?
When a solid changes state directly into a gas, we say it will sublime, or undergo sublimation.
Can solid carbondioxide sublime on heating?
Yes, solid carbon dioxide, also known as dry ice, can sublime directly from a solid to a gas when heated. This means it skips the liquid phase and turns directly into carbon dioxide gas. Sublimation occurs because the pressure and temperature conditions allow the solid to transition directly into a gas.
