What involves changes of solid to vapor but no liquid is form?
sublimination
When a solid is converted directly to a gas the change in state is called?
sublimination
When a substance exists as a liquid or solid under ordinary conditions its gas phase is called a?
It's called sublimination
What is the Sublimination?
Sublimation is when a solid turns into a gas... when water turns into ice it solidifies... when ice turns into water it melts... when ice turns into steam it is sublimation.
What rule can you state about the relationship between phase chages and temperature?
Phase changes absorb or release heat energy. Condensation (from gas to liquid or gas to solid) releases the most heat. The gas molecule, flying around at the speed of sound, had more energy than when it is condensed in a liquid. That difference in energy is released as heat. That's why a steam burn can be so bad - it is a lot of heat. Evaporation (liquid to gas) and sublimination (solid to gas like dry ice reating a CO2 fog) absorb heat. That's why sweating cools you. The water absorbs a lot of heat as it evaporates. The energy amounts are equal and opposite of condensation. Melting (solid to liquid) absorbs heat and freezing releases heat. So your freezer must pump heat out of the ice tray to make ice cubes. Those ice cubes, when in a drink, cool the drink by absorbing heat as they melt.
What happened during sublimination?
During the process of sublimination energy is eliminated.
What do you call it when a solid changes to liquid when skipping melting?
Sublimination
What involves changes of solid to vapor but no liquid is form?
sublimination
When a solid is converted directly to a gas the change in state is called?
sublimination
What three phase changes require the addition of heat?
I think melting, condensation and Sublimination.
Why do mothballs disappear at room temperature?
This process is called Sublimination which means a solid state changes to a gaseous state.
When a substance exists as a liquid or solid under ordinary conditions its gas phase is called a?
It's called sublimination
What process takes place when matter changes from state 1 to state 3?
if u are talking about a solid to a gas then it is called sublimination
How can coal be turned into a gas or liquid?
Coal, as a form of carbon has no liquid phase it will go strait to gas in a process called sublimination at about 5800k.
List three mixtures commonly used to separate mixtures into their component substances?
Filtration, distillation, crystallization. Sublimination or chromotography could be used as well.
What are the changes in state and states of matter?
Solid to liquid is melting Liquid to Gas is evaporation Solid to gas is sublimination Liquid to solid is freezing Gas to liquid is condensing
What is a called solid changing into a gas without no liquid phase?
I believe it is called "sublimination" this link has a great, um, graphmobob illustrationization. I mean "phase diagram" http://www.chemprofessor.com/phase.htm
