Gas pressure (in a container, for example) is due to the atoms or molecules bumping against the walls of a container. At absolute zero, the molecules have no internal energy, no speed - they won't move.
In practice, you can approach absolute zero, but you can never quite reach it.
What else can I help you with?
What is the temperature at which an ideal gas occupies zero pressure?
The temperature at which an ideal gas occupies zero pressure is called absolute zero. It is defined as 0 Kelvin or -273.15 degrees Celsius. At this temperature, the particles in the gas have minimal kinetic energy and do not exert any pressure.
What happens to the molecules of the trapped gas when its height in the tube becomes zero?
When the height of the trapped gas in the tube becomes zero, the gas molecules continue to move freely within the tube. Since no more gas can flow into or out of the tube, the pressure inside the tube increases. The gas molecules exert pressure on the walls of the tube evenly in all directions.
What pressure would you expect in a rigid container of 0 degrees Celsius gas if you cooled it by 273 degrees Celsius?
The pressure would decrease to zero because a gas at 0 degrees Celsius is frozen, and frozen gas does not exert any pressure due to lack of molecular motion.
What is the temperature is the gases are at zero volume?
At zero volume, according to the Ideal Gas Law, the temperature of the gas would theoretically be infinite. This is because at zero volume, the pressure of the gas would be infinite, leading to an infinite temperature according to the gas law equation. However, this scenario is not physically possible as gases will always occupy some volume.
What is absolute zero pressure?
absolute pressure is calculated from a vacuum (0 psi) and atmospheric pressure is14.7psia or 14.7 psi above a vacuum 1psi on a tire pressure gauge is called 1psig = 15.7psia 10psig=24.7psia 100psig=114.7psia etc.
What is the temperature at which an ideal gas occupies zero pressure?
The temperature at which an ideal gas occupies zero pressure is called absolute zero. It is defined as 0 Kelvin or -273.15 degrees Celsius. At this temperature, the particles in the gas have minimal kinetic energy and do not exert any pressure.
Why would the pressure be 0 for absolutle zero?
The pressure of a gas is exerted on the walls of its container by the movement of the molecules making up the gas. The higher the temperature, the faster the particles move, increasing the pressure exerted on the sides of the container. As the temperature decreases, the movement of the gas particles slows down, reducing the pressure. At absolute zero, the gas particles would be completely frozen so that no particles would be hitting the sides of the container and the pressure exerted by the gas would be zero. This is all theoretical since absolute zero cannot yet be reached, and gas would not actually be able to have a pressure of zero.
If a certain amount of gas fills a 1.0 liter container and exerts a pressure on the walls of 2.0 Nm2 at 20 degrees celsius what would the pressure theoretically be at absolute zero?
Zero. PV = nRT. T = 0, so nRT = 0, and thus PV must be zero also. Since we know the volume is not zero, the pressure must be zero.
What would the volume and pressure of an ideal gas be at absolute zero temperature IF an ideal gas actually existed?
Here's the ideal gas law: PV = nRT If T is zero, then PV must be zero; assuming the volume is nonzero, then for PV to be zero the pressure must be zero. However, this is only true for an ideal gas. For a real gas other factors come into play at low temperatures, and they begin to deviate from the ideal gas law. Also, all real gases liquify above absolute zero, and liquids don't obey the ideal gas law at all.
Could the volume of a gas ever be equal to zero?
No.
What pressure would you expect in a rigid container of 0 centigrade gas if you cooled it by 273 centigrade?
If you cool the container to -273 degrees Celsius, which is absolute zero, the gas would theoretically have zero pressure since all molecular motion would cease. In practice, achieving absolute zero is impossible, but as you approach it, pressure would approach zero.
How to measure the pressure of a gas in atmospheres at different temperatures in C Can you predict the temperature at which the pressure would equal zero?
To measure the pressure of a gas in atmospheres at different temperatures in Celsius, you can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin. To predict the temperature at which the pressure would equal zero, you would need to decrease the temperature below the gas's critical temperature, at which point the gas would liquefy and the pressure would drop to zero.
Why will pressure or volume never equal to zero?
Pressure and volume cannot be equal to zero because absolute zero pressure and volume represent the absence of matter or particles. In reality, there will always be some amount of gas particles present, even if it is very low, which will result in a non-zero pressure and volume.
What happens to the molecules of the trapped gas when its height in the tube becomes zero?
When the height of the trapped gas in the tube becomes zero, the gas molecules continue to move freely within the tube. Since no more gas can flow into or out of the tube, the pressure inside the tube increases. The gas molecules exert pressure on the walls of the tube evenly in all directions.
What is the volume of gas when the temperature is 0 Celsius?
Answer: computer says no?Answer: Also zero. This is hypothetical; an extrapolation. No real substance can be cooled all the way to zero Kelvin, and no gas would remain a gas at temperatures approaching that temperature.
How cold is ultimate zero?
Absolute zero is -273 degrees Celsius A: Actually, absolutely zero reflects a state in which an ideal gas exerts no pressure on its containment. As gas pressure come from movement, this temp depends on which components of the gas you're looking at: molecules, atoms, sub-atomic particles, etc. We have dropped electrons down as far as one picokelvin as of this writing. The actual number for ultimate zero, then, is not truly obtainable and is a theoretical constant.
What pressure would you expect in a rigid container of 0 degrees Celsius gas if you cooled it by 273 degrees Celsius?
The pressure would decrease to zero because a gas at 0 degrees Celsius is frozen, and frozen gas does not exert any pressure due to lack of molecular motion.
