You may currently know that space three key “states”of matter: gases, liquids, and solids (there arereally four, yet that is besides the point). Yourquestion is questioning which solids experience thesolid-to-gas transition, sublimation.

You are watching: Which sample of matter sublimes at room temperature and standard pressure

even if it is or no a solid will certainly sublime relies on anumber that factors. Sometimes, a solid will certainly favorgoing to the fluid state before the gas stateand various other times a chemical reaction will occurbefore the temperature can be raised high enoughto acquire the original molecules in the gas state.There is a subject referred to as thermodynamics thatallows united state to find the temperatures at i beg your pardon solidswill turn into liquids and gases and also thetemperatures in ~ which chemistry reaction can occur.If a chemistry reaction does no occur and theliquid state is not favored end the gas state asyou advanced the temperature, the solid will sublime.

think about a couple of solids: ice, i beg your pardon is madeout of water molecules, dry ice, make from carbondioxide molecules, and wood, make from cellulosemolecules.

First, imagine we take a item of ice and also setit exterior on a sunny day. We an alert that the icebegins come melt and also eventually all we have left isa pool of water. If us wait also longer us seethat the pool of water has disappeared.

Essentially, ice prefers to adjust into theliquid state an initial before evaporating into thegaseous state. (*Note this is not totally true!Even ice and snow sublime come a particular extentbefore changing in the fluid state!)Now imagine us take a item of dried ice and also lay itoutside ~ above a clear day. If she not sure whatdry ice cream is, you might want to youtube dry ice. Inthis case we watch that the dry ice starts tovaporize straight from the heavy state!

Finally, we lay the wood outside on a sunny day.Nothing happens of food and, being thescientists we are, we decide that us must warmth thewood even an ext to shot to do it into a gas.However, as shortly we warm the wood, because that instancewith a match or a lighter, we watch that the woodcatches fire. This is an instance of a chemicalreaction, wherein cellulose molecule in the woodand actually being convert into amongst otherthings, carbon dioxide, the ingredient of dry ice cream andwhat us breathe out.

Examples the solids that sublime space dry ice(solid carbon dioxide), iodine, arsenic, andnaphthalene (the ingredient mothballs are made of).This is a great question that is more complicated toanswer 보다 you would suspect. If friend areinterested in finding out more, please totally free to ask.

Best, Answer 2:

Any solid may be sublimed if the temperature andpressure are listed below its triple point. For example,if you to be to freeze water into ice and cool itfurther and then alleviate the pressure, you couldget ice to sublime. Part other examples include:Dry ice (solid CO2) i m sorry sublimes at atmosphericpressure and -78 C, and C60 (buckyballs) whichsublimes at atmospheric pressure at about 800 K.

Answer 3:

Some common solids go v sublimation atstandard push (1 atmosphere). Carbon dioxidesublimates in ~ -78.5 °C (-109.3 °F), and also we usethis “dry ice” because that cooling purposes. Iodine isanother substance that has actually been observed tosublimate at room temperature and also pressure.Naphthalene, a chemical v numerousapplications, sublimates at roughly 80 °C(176 °F). A problem which generally doesn’tsublimate (i.e. Water) at typical pressure deserve to bemade come sublimate at reduced pressures. The phaserelationships of a chemical space expressed top top aphase diagram through pressure and also temperature as thetwo axes.

Answer 4:

A number of solids are capable of sublimating atnormal temperatures and also pressures, including snow,iodine, arsenic, and solid carbon dioxide (dryice). Occasionally other materials have the right to be do tosublimate by producing low press conditions.

If you take it a products science course in thefuture (probably in college), climate you will learnto check out "phase diagrams," which space basicallygraphs that show what temperatures and also pressuresare required to have actually solid, fluid or gas phasesfor a material. You deserve to see from these diagramswhether or no there is an accessible transitiondirectly from solid to gas for any material. Thistells you even if it is or not a product is capable ofsublimating.

Answer 5:

Almost all solids have the right to go with sublimation,under particular conditions. This just means thesolids go directly to gasses without becomingliquids first. Typically solids undergosublimation at short pressures (under vacuum). Atstandard, atmospheric pressure, a few solids whichwill sublime space iodine (at slightly higher thanroom temperature), carbon dioxide (dry ice) at-78.5 levels Celsius, and naphthalene(used in mothballs) and arsenic.

Answer 6:

All solids sublime. The rate of sublimationdepends top top temperature, wait pressure, and thesolid in question. Water ice cream is the one the wethink of the sublimes most readily.
