Sublimation is accelerated at high temperature.
The halogen that undergoes sublimation at room temperature is iodine.
Every element has its own temperature of sublimation.
The relationship between temperature and sublimation pressure in a solid substance is that as temperature increases, the sublimation pressure also increases. This means that at higher temperatures, the solid substance is more likely to change directly into a gas without passing through the liquid phase.
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.
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.
Bleaching 100% polyester fabric before sublimation printing is NOT recommended, and here's why: Why You Shouldn't Bleach Polyester Before Sublimation: Polyester is a synthetic fabric — bleaching it can damage the fibers, leading to: Yellowing or discoloration Weakening of the material Uneven surface for sublimation Sublimation needs a stable, high-polyester surface — bleaching may interfere with how well the ink bonds with the fabric. What You Can Do Instead: Start with white or light-colored 100% polyester fabric – this gives the best sublimation results without needing any bleaching. If you want a “bleached” look , use bleach spray techniques on cotton-blend shirts (like 65% polyester / 35% cotton), but: Do it after dye sublimation printing. Be aware that sublimation colors will fade more on blends. Do not bleach 100% polyester before sublimation. It’s better to choose white polyester fabric and apply your design directly for vibrant, long-lasting results. Let me know if you're trying to get a certain look, and I can suggest safe alternatives!
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
If there is high pressure, the sample is physically prevented from easily making the phase change at a constant temperature. PV= nRT solid --> liquid --> gas S-->L at high pressure decreases the mp L -->G at high pressure increases the bp and the temp at vaporization Analogous to glaciers melting, ice under high pressure will melt. Analogous to boiling an egg in Boston (sea level) or in Denver (1 mile above sea level). Which takes longer? Boston, b/c the the pressure at sea level is greater, so the bp is higher. In Denver, there is less vapor pressure (ie, the air above the pot with the egg), so the temp of boiling is lower.
Sublimation occurs when solid changes directly to liquid without changing to solid state. Applying pressure and reducing temperature can liquefy gases.
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
The temperature and pressure are two factors that affect the states of matter. Changing the temperature can cause a substance to change from solid to liquid to gas, and adjusting the pressure can also impact the state of matter, such as in the case of phase transitions like sublimation or deposition.
