What type of reaction is sublimation?
Sublimation is not a reaction, but a physical change (change of state or phase). The solid turns instantly to gas, rather than first going to liquid state. At the right temperature and pressure, this can happen. A common example of this is dry ice (solid carbon dioxide) turns to carbon dioxide gas without first going through the liquid phase. This occurs, because liquid carbon dioxide cannot exist at 1 atmosphere pressure. Sublimation can happen with solid water (ice) as well, at the right temperature. Ice cubes in a freezer can seemingly disappear over time.
What material changes from a solid to a gas?
The most well known is dry ice, which changes directly from solid carbon dioxide into the gaseous state. Water can change directly from ice into water vapor (a dry wind blowing over a snow bank will reduce its volume as the frozen water changes directly into water vapor). These are examples of sublimation.
What is the heat of sublimation of Iodine at 297 K?
The heat of sublimation for iodine over the range of temperatures from 273 K to 368 K has been reported in the literature: D. A. Shirley and W. F. Giauque, J. Am. Chem. Soc. _81_, 4778-4779 (1959). Table III of that reference contains the information you'll need.
Naphthalene balls disappear with time without leaving solid why?
The "moth balls" perform an action called "Subliming". That is, they go from a solid state directing to a gaseous state. This is the same thing that 'Dry Ice' does. Dry Ice is solid CO2 , and does not melt into a liquid state, but rather it goes from solid to gas directly.
How do naphthalene balls become smaller. name the process?
Naphthalene balls decrease in size due to sublimation, a process where the solid naphthalene directly transitions into a gas without passing through the liquid phase. This gradual transition causes the naphthalene balls to shrink over time.
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
How do you spell skipped?
That is the correct spelling of the word "skipped" (passed over, or gamboled).
What happens when sublimation takes place?
Sublimation is the change of state of matter from solid directly to gas. Dry ice does this. Deposition is the change of state from gas to solid. This is how frost forms. There are likely more examples of each, but they both skip over the liquid state of matter.
Is a chemical change an example of a sublimation?
Sublimation is a physical change, not a chemical change. The best known example is when dry ice, which is solid carbon dioxide, turns into a vapor, which is just carbon dioxide gas. It skips over the liquid phase. Because you're just changing from one state of matter to another, it's a physical change just like melting ice or boiling water.
How do you do skipping?
That is the correct spelling of the word "skipped" (passed over, or gamboled).
When ice cube slowly vanish from tray is the example of?
When an ice cube slowly disappears from the ice tray in the freezer, that is sublimation. The solid water (ice) is turning directly to the gas state (water vapor)- it skips over the liquid phase.
What are the 4 phases that changes solid liquid gas and plasma?
There are five common state changes between the three common states of matter. They are melting (solid to liquid), freezing (liquid to solid), condensation (gas to liquid), evaporation (gas to liquid) and sublimation (solid to gas, gas to solid).
Over timemothballs disappear into the air as gas is?
Your question makes no sense, but if I had to guess at what you're after, the answer may be sublimation.
What is the name after the forerunner of the Greek gods?
The answer is achilloa.She is the god of indigestion and diarrhea, commonly skipped over in the world.
Why Internet is pronounced like INNERNET in informal American English?
When speaking quickly the T is often skipped over.

Why do people trip over nothing?
because they don't know how to walk they skipped a stage in life;) smiley face cheese
