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.
What else can I help you with?
Why is sublimation rare and what are the conditions in which it typically occurs?
Sublimation is rare because it requires specific conditions of temperature and pressure for a substance to change directly from a solid to a gas without passing through the liquid phase. Typically, sublimation occurs at low pressures and temperatures where the substance's vapor pressure exceeds its triple point pressure.
When a solid changes directly into a gas a change called occurs.?
Sublimation is the change when a solid transforms directly into a gas without passing through the liquid state. This process occurs when the temperature is above the substance's triple point and the pressure is lower than the substance's vapor pressure.
How does sublimation work in science?
Sublimation is the process of a solid to gas without being turned into a liquid. One must find a phase diagram of the substance. The triple point where all three phases can mannerly exist. So when one finds point below this, and a pressure and temperature where liquid doesn't exist the solid will become gas.
When something goes from a solid directly to a gas what is it called?
The process of a substance changing from a solid directly to a gas is called sublimation. This occurs when the substance's vapor pressure exceeds its atmospheric pressure at a certain temperature, allowing it to transition from a solid state to a gaseous state without passing through the liquid phase.
How do you draw a sublimation curve?
To draw a sublimation curve, plot temperature on the x-axis and pressure on the y-axis. Follow the curve that shows the conditions where the substance transitions directly from solid to gas without passing through the liquid phase. The curve slopes upward as pressure increases, indicating the sublimation point.

Typically, sublimation occurs at low pressures and temperatures where the substance's vapor pressure exceeds its triple point pressure.
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 is the graph of a relationship between the physical state of a substance and the temperature and pressure of the substance?
Phase diagram?
Why the matter in sublimation converted from solid to vapor without passing in liquid phase?
The phase of any given substance is governed by two factors, temperature and pressure. Everything has a liquid phase, in the right temperature range if the pressure is high enough. If the pressure is not high enough, you get sublimation.
When a solid changes directly into a gas a change called occurs.?
Sublimation is the change when a solid transforms directly into a gas without passing through the liquid state. This process occurs when the temperature is above the substance's triple point and the pressure is lower than the substance's vapor pressure.
Two factors that are responsible for a phase change?
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
How does sublimation work in science?
Sublimation is the process of a solid to gas without being turned into a liquid. One must find a phase diagram of the substance. The triple point where all three phases can mannerly exist. So when one finds point below this, and a pressure and temperature where liquid doesn't exist the solid will become gas.
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.
What is the explanation for the chemical meaning of sublimation?
Sublimation is the process in which a substance passes from the solid phase directly to the gas phase without passing through a liquid phase. Iodine is an example of a substance that sublimes.
When something goes from a solid directly to a gas what is it called?
The process of a substance changing from a solid directly to a gas is called sublimation. This occurs when the substance's vapor pressure exceeds its atmospheric pressure at a certain temperature, allowing it to transition from a solid state to a gaseous state without passing through the liquid phase.
Process in which a substance changes from solid to gas?
Sublimation is the process in which a substance changes directly from solid to gas phase without passing through the liquid phase. This occurs when the vapor pressure of the solid exceeds its atmospheric pressure at a certain temperature. Examples include dry ice (solid carbon dioxide) and mothballs (solid naphthalene) sublimating at room temperature.
How do you draw a sublimation curve?
To draw a sublimation curve, plot temperature on the x-axis and pressure on the y-axis. Follow the curve that shows the conditions where the substance transitions directly from solid to gas without passing through the liquid phase. The curve slopes upward as pressure increases, indicating the sublimation point.
