What else can I help you with?
How can you decrease pressure of a gas in its container without changing the volume of gas?
lots of ways 1. cool it down 2. give it more space 3. remove some gas
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 happens to iodine at room temperature?
Iodine is a solid at room temperature and pressure. It sublimes, meaning it changes directly from a solid to a gas without passing through a liquid phase.
What sample of matter sublimes at room temperature and standard pressure?
Dry ice (solid carbon dioxide) sublimes at room temperature and standard pressure, meaning it changes directly from a solid to a gas without passing through the liquid phase.
What is a direct change from a solid to a gas?
Sublimation is the direct change from a solid to a gas without going through the liquid phase. This process occurs when the solid's vapor pressure exceeds the atmospheric pressure at a specific temperature.
Rocks can melt without changing temperature when the pressure exerted on them is .?
Increase
What can happen if you had a sudden drop on boiler steam pressure without a corresponding drop in boiler water temperature?
BOILER EXPLOSION- Caused by a sudden drop in pressure (failure on the steam side) without acorresponding drop in temperature.
What can melt rocks without changing temperature when their confining pressure?
The process of partial melting can occur in rocks under high confining pressure, where the minerals in the rock start to melt without the overall temperature changing. This happens because the pressure lowers the melting point of the minerals. The supercritical fluids in Earth's mantle can also cause rocks to melt without a change in temperature under the high pressure conditions.
How can you make a liquid boil without raising its temperature?
Reduce the surrounding pressure. Lowering the pressure on a liquid reduces its boiling point, causing it to boil at a lower temperature.
Is thulium a solid a liquid or gas?
This cannot be answered without the temperature and pressure having been provided. At Standard Temperature and Pressure thulium is a solid. It melts at 1545 °C and boils at 1950 °C at standard pressure (101.325 kPa).
Does pressure cause heat in a closed system?
In a closed system, pressure can cause heat through a process called adiabatic heating. This occurs when the pressure of a gas in the system increases, leading to an increase in temperature without any heat being added or removed from the system.
What the device used to increase the temperature of the saturated steam without increasing its pressure is called?
There is a small problem with the question: if you increase the temperature of saturated steam without increasing pressure, it will no longer be saturated - it will be superheated. With this in mind, it should be no surprise that the device that does this is normally called a "superheater". The picture accompanying this question is an example of a superheater.
