Low pressure reduces the pressure exerted on the solid, allowing the molecules to escape more easily through sublimation. Lower temperature helps to maintain the solid state's stability by reducing the energy available for the molecules to transition directly from solid to gas phase. Together, low pressure and temperature facilitate faster sublimation by promoting the direct transition of molecules from solid to gas.

A student is studying how the air pressure in a basketball depends on its temperature what measuring instruments are needed for this experiment?
To study how air pressure in a basketball changes with temperature, you will need a pressure gauge to measure the air pressure inside the basketball accurately. Additionally, you will require a thermometer to monitor the temperature of the basketball during the experiment.
How do you know when it use PVnRT?
You should use the ideal gas law equation PV = nRT when dealing with situations involving gases at a constant temperature and pressure, where you need to calculate the volume, pressure, moles, or temperature of the gas.
What is 47.3 kPa converted into degrees Celsius?
Pressure cannot be directly converted into temperature as they are different units of measurement. Pressure is typically measured in pascals (Pa) or kilopascals (kPa) whereas temperature is measured in degrees Celsius (°C). To convert pressure to temperature, you would need additional information such as the volume and the ideal gas law.
A cylinder pf gas at room temperature has a pressure of p1. To what temperature Celsius would the temperature have to be increased for the pressure to be 2.2p1?
It would have to be increased to 2.2 times absolute room temperature.Absolute room temperature is about 20°C, or about 293K.(2.2) x (293) = 644.6K or 371.6°C . (about 701°F.)
How much steam pressure would a five inches diameter by twelve inches long with six inches of water in it?
To calculate the steam pressure in the container, you would need additional information such as the temperature of the water and the volume of the container. The pressure would be determined by the temperature and volume inside the container following the ideal gas law. Without more details, it is not possible to provide a specific pressure value.
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 is sublimation point?
Salt ... ordinary table salt ... melts rather than sublimes at normal pressures. To find the sublimation point, you'd need to specify a pressure and look at a phase diagram. The sublimation point would be the point on the solid/gas phase boundary where the pressure is equal to your specified pressure. I'm sorry I can't be more exact, but that's just the way it is; normally when people talk of "melting points", "boiling points", or "sublimation points" it's assumed that they're talking about a system at "standard pressure" (about 100 kPa), and sodium chloride does not sublime at that pressure at any temperature.
At what temperature does dry ice sublimate?
At Earth's standard pressure (1 atmosphere or atm), dry ice sublimes at −78.5 °C , which is −109.3 °F.
What is the change of a substance from a solid directly to gas?
The process is called sublimation. Solids can turn directly into gases, and gases can turn directly into solid without ever being a liquid. Carbon dioxide (dry ice) is a common example of this. Other examples are mothballs, solid air fresheners (Air Wick), and iodine.
What is the proccess of a gas to a solid?
The process is sublimation:] if you need this for a project google gas to solid sublimation
Doug wants to find out how increasing a gas's pressure can affect the gas's temperature What tool will Doug need in order to conduct his experiment?
Doug will need a pressure gauge to measure the pressure of the gas, a temperature gauge to measure the temperature of the gas, and a container to hold the gas while adjusting the pressure.
I need to know how many milliters for eight millgrams.?
you need to know the density, temperature and pressure for water at standard temperature and pressure then 8mg = 8ml for other liquids/temperatures it will be different
What is happening to energy in sublimation?
Sublimation is an endothermic phase transition.Sublimation is the transformation of a solid in a gas, directly, and need energy for this.
What freezes faster water or ammonia?
Water freezes faster than ammonia because water has a higher freezing point (0°C) compared to ammonia (-77.7°C). This means that water can freeze at a higher temperature, making the freezing process faster.
Which of these factors does not need consideration when determining air pressure?
Temperature does not need to be considered when determining air pressure. Air pressure is mainly affected by altitude and atmospheric conditions, such as humidity and weather systems. Temperature can affect air pressure indirectly by influencing density and vertical movement of air masses.
What is the maximum pressure schedule 40 galvanized pipe can take?
Need to know the pipe diameter. 3 inch is the diameter of the galvanized pipe what is the working pressure of the pipe
