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.
Is nitrogen gas at high temperature and pressure flammable is there is no temperature and pressure at which nitrogen gas can be flammable?
Nitrogen gas is not in itself flammable, and does not have an auto ignition temperature.
Can a solid be turned straight into a gas and how?
Yes, a solid can be turned directly into a gas through a process called sublimation. Sublimation occurs when the solid changes into a gas without passing through the liquid phase. This can happen under specific temperature and pressure conditions.
What phase is liquid nitrogen in at room temperature?
Liquid nitrogen is liquid.
Is nitrogen hot or cold?
Nitrogen is a gas at room temperature and pressure, so it doesn't have a specific temperature. When liquid nitrogen is in contact with objects at room temperature, it can appear very cold because of its extremely low temperature of around -196 degrees Celsius.
How temperature affect sublimation?
Sublimation is accelerated at high temperature.
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 nitrogen a solid?
Nitrogen can be obtained as a solid at very low temperature, under -210 0C. At room temperature nitrogen is a gas.
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.
Is nitrogen gas at high temperature and pressure flammable is there is no temperature and pressure at which nitrogen gas can be flammable?
Nitrogen gas is not in itself flammable, and does not have an auto ignition temperature.
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.
Can boiled water sublimate at extremely cold temperature?
Yes, the sublimation is possible.
