What else can I help you with?
What cannot be separated by sublimation?
Sublimation is the process of turning a substance from a solid directly into a gas without passing through the liquid state. Some substances like certain polymers and complex mixtures cannot be separated by sublimation because they do not have a clear melting point or do not sublime easily.
When substances go directly from the solid phase to the gas phase the phase change is called?
sublimation
What solid can turn into a gas without becoming a liquid?
This process is called sublimation. Some common substances that exhibit sublimation are dry ice (solid carbon dioxide) and camphor.
Can you separate mixtures of ammonium chloride and naphthalene by sublimation?
yes but only by fractional sublimation (sublimating point of these substances are different)
Can iodine and naphthalene be separated by sublimation?
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
What is fractional sublimation?
Sublimation refers to a substance changing from a solid directly into a gas, and can usually only be achieved via decrease in air pressure as well as temperature. Fractional sublimation refers to separating a substance's parts through the sublimation of one part.
The change in state from a solid directly to a gas without passing through the liquid state?
This process is known as sublimation. Sublimation occurs when a substance goes from a solid to a gas without passing through the liquid state. Examples of substances that undergo sublimation include dry ice (solid carbon dioxide) and mothballs (paradichlorobenzene).
Which substances show sublimation at atmospheric pressure?
Common substances that exhibit sublimation at atmospheric pressure include carbon dioxide (dry ice) and iodine. These substances transition directly from solid to gas phase without passing through the liquid phase under normal atmospheric conditions.
When substances change from a gas to a liquid what process is that?
This process is called condensation.
Can sublimation of a substance be utilized to separate it from other substances?
Yes, it is possible if one of the substance will sublime and others will not.
Most solids pass through the liquid state as they turn to gas?
Most do. Other substances like I2 go directly for a solid to a gas. This is called sublimation. The opposite of sublimation is deposition
What are 2 solid substances that don't go through a liquid state when heated and go straight to gas?
Naphthalene and camphor the process is sublimation
