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.
The temperature at which the volume of a gas theoretically becomes zero is called?
The temperature at which the volume of a gas theoretically becomes zero is called absolute zero. It is equal to 0 Kelvin or -273.15 degrees Celsius. At this temperature, the particles in a gas would have minimal kinetic energy and would theoretically cease all motion.
What does the absolute temperature scale use as its reference temperature?
-459.67 F Which is absolute zero and that is the temperature at which all molecular activity stops.
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 temperature scale has a zero its lowest temperature?
The Kelvin scale has a zero at its lowest temperature, known as absolute zero. At absolute zero, atoms and molecules cease to move, resulting in zero thermal energy.
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.
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.
Would air ever have zero volume at absolute zero?
No, at absolute zero there would still be some volume occupied by the air molecules. Although the volume would decrease as temperature approaches absolute zero, it never reaches zero due to the Heisenberg Uncertainty Principle, which states that we can never know both the exact position and momentum of a particle simultaneously.
How is absolute zero originally determined?
The volume of gases decreases with temperature; extrapolating the volume/temperature relationship, it looked as if all gases would reach a volume of zero at approximately the same temperature, about minus 273 degrees centigrade.
What is the zero point on the absolute scale defined as?
SZero point in the absolute scale is the temperature at which the kinetic energy of the molecule becomes Zero. For a constant pressure volume would become zero and at constant volume pressure would become zero at this absolute zero temperature.
Why you use kelivin in calculation instead of celsius and Fahrenheit?
Kelvin has the advantage that it is an absolute temperature scale - it starts from absolute zero. This simplifies several calculations; for example, in an ideal gas, at constant pressure, the volume of the gas is proportional to the absolute temperature. Similarly, calculations related to heat machines are simpler if an absolute temperature scale is used.
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 many times have scientist gotten an object to the temperature of absolute zero?
Never. They've gotten an object to a fraction of a degree above absolute zero, but absolute zero is physically impossible. If you look at the ideal gas law, PV=nRT, where T is temperature and V is volume, if T were ever 0, volume must also equal 0. So in theory, if an object ever got down to 0 degrees, it must also have 0 volume. 0 volume means it isn't there, so reducing an object's volume to 0 would be equivalent to making it disappear, which is impossible. therefore, reaching absolute zero is physically and theoretically impossible.
How can charle's law be used to determine absolute zero?
Charles's Law states that the volume of a gas is directly proportional to its temperature at constant pressure. By extrapolating the relationship between volume and temperature to a point where the volume approaches zero (absolute zero), the temperature at which this occurs can be determined. This temperature is considered to be absolute zero, the theoretical lowest temperature possible.
What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
Justify that the volume of given mass if a gas becomes theoretically zero at -273c?
At -273°C, a gas would reach absolute zero on the Kelvin scale, which is 0K. At this temperature, all molecular motion stops, causing the volume of the gas to theoretically become zero. This is because gases have negligible volume and are assumed to occupy zero volume at absolute zero.
What is temperature of absolute zero in kelvin?
Absolute zero in Kelvin is defined as 0 degrees. This is -273.15 degrees celcius. It was determined by extrapolating the gas and pressure of an ideal gas as it approaches the point where all of its particles stop vibrating. The closest we have gotten to absolute zero is 10^-15 degrees kelvin. Hope that helps.
