Sublimation is accelerated at high temperature.
What else can I help you with?
The halogen that undergoes sublimation at room temperature is?
The halogen that undergoes sublimation at room temperature is iodine.
What temperature does a solid turn into a gas?
Every element has its own temperature of sublimation.
What is the relationship between temperature and sublimation pressure in a solid substance?
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.
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.
Why should you use sublimation to separate the mixture of salt and ammonium chloride?
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
Is burning woo sublimation?
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.
What factors affect sublimation?
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.
What type of phase change is happening as a solid changes to gas without becoming to a liquid?
Sublimation occurs when solid changes directly to liquid without changing to solid state. Applying pressure and reducing temperature can liquefy gases.
How does the temperature of water affect the sublimation of dry ice?
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
What two factors affect the states of mater?
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.
Can boiled water sublimate at extremely cold temperature?
Yes, the sublimation is possible.
