Solids that can turn directly into gas without melting first undergo a process called sublimation. Common examples include dry ice (solid carbon dioxide), iodine, and naphthalene. In these cases, the solid transitions directly to vapor when heated, bypassing the liquid phase. This phenomenon occurs under specific temperature and pressure conditions.
What else can I help you with?
When ice changes into water vapor must it melt first?
No - ice can go straight to vapor without first melting. The process is known as "sublimation".
What are examples of solids that will turn into liquids?
Ice melting is probably the most common sight
When ice changes into water vapor without first melting?
It is called sublimation.
What is the phase change that occurs when a solid goes directly to a gas without melting first?
The phase change is called sublimation. In this process, a solid changes directly into a gas without passing through the liquid phase.
If you live in a very cold area you may have seen the depth of a bank of snow shrink even though temperatures remain below the melting point of water how might you account for this observation?
The process is called sublimation, where snow turns directly into vapor without melting first. In cold temperatures, snow can still lose mass through sublimation, causing the bank of snow to shrink even without reaching the melting point of water.
When ice changes into water vapor must it melt first?
No - ice can go straight to vapor without first melting. The process is known as "sublimation".

What is the process called when solids vaporize without becoming a liquid first?
volitilize
What is the change of solid to gas without melting first?
It is called 'sublimation'.
Is it true or false that solids can go directly into the gas phase without becoming a liquid first?
False. Solids cannot go directly into the gas phase without becoming a liquid first. This process is known as sublimation, where a solid turns into a gas without passing through the liquid phase.
When ice changes into water vapor without first melting?
It is called sublimation.
What is the word for ice changing into water vapor without melting first?
The word for a solid turning into a gas without going through the liquid phase is - sublimation.
Can solids evaporate?
Only certain solids evaporate. Most solids melt before evaporating. When a solid turns straight into a gas, it is called sublimation. Examples of substances that sublime include carbon dioxide, iodine, arsenic, and naphthalene.
Who descoverd the platonic solids?
We don't know for certain who discovered the platonic solids first. However, Pythagoras is credited by some sources as discovering the platonic solids first. Other sources credit Theaetetus as being the first to describe all five platonic solids and proving that these are the *only* platonic solids.
How can snow evaporate?
Snow can evaporate through a process called sublimation, where the solid snow turns directly into water vapor without melting into liquid water first. This happens when the snow is exposed to dry air and sunlight, causing it to slowly disappear without melting.
What element of the first eighteen elements has the highest melting point?
Carbon (C) has the highest melting point out of all the elements, and so, as it's in the first 20 elements, it has the highest melting point of the first 20 elements too. Its melting point is 3823K.
Is lithium a solid at boiling point?
No. Solids do not boil, but they may sublime, which is when a solid goes directly into the gas phase without melting first. However, lithium does not sublime. Its melting point is 180.54 degrees Celsius, and its boiling point is 1342 degrees Celsius. So lithium is a liquid before reaching its boiling point.
