What else can I help you with?
Is it possible for absolute pressure to be negative?
No, absolute pressure cannot be negative as it is always measured as a positive value above zero.
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 is the absolute value of the blood pressure gauge reading?
The absolute value of the blood pressure gauge reading is the positive value of the number shown on the gauge, regardless of whether it is above or below zero.
The absolute value of zero is?
Zero.Zero.Zero.Zero.
Which term is defined as the atomospheric pressure at sea level at zero degress celsius?
The term you're looking for is "standard atmospheric pressure," which is defined as the atmospheric pressure at sea level at zero degrees Celsius. It is commonly used as a reference point for pressure measurements in meteorology and other fields.
Why absolute pressure is always positive?
Absolute pressure is always positive because it measures pressure relative to a perfect vacuum, which is defined as having zero pressure. Since absolute pressure accounts for all atmospheric and additional pressure above this vacuum level, it cannot fall below zero. Consequently, even in a vacuum, absolute pressure is defined as zero, ensuring that any measurement of absolute pressure is either zero or a positive value.
What would be the pressure at absolute zero?
o
What would be the pressure theoretically at absolute zero?
o
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.
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.
Is it possible for absolute pressure to be negative?
No, absolute pressure cannot be negative as it is always measured as a positive value above zero.
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 you have obtained a different temperature for absolute zero if you recorded the pressure in psi instead of kpa?
No, the temperature for absolute zero would remain the same regardless of whether pressure is recorded in psi or kPa. Absolute zero is defined as 0 Kelvin, which corresponds to a theoretical temperature where molecular motion ceases. While pressure measurements in different units may yield different numerical values, they do not affect the fundamental physical properties of temperature and absolute zero.
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.
What is a Vacuum in kilo pascal?
Depends on If it's absolute or relative. Vacuum in any unit is zero in absolute pressure. Vacuum in any unit is -normal air pressure in relative pressure.
Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
Zero gauge pressure equals what pressure on the absolute pressure scale?
Zero (0) gauge pressure equals 14.696 PSI on the absolute scale. A lot of people will round up to 14.7 PSI for simplicity. 14.696 PSI is the pressure that is developed at sea level due to the weight of our atmosphere. The absolute pressure scale is based on zero being a perfect vacuum. Gauge pressure takes into account the atmospheric pressure at sea level (14.696 PSI). A simple conversion formula is PSIG+14.696=PSIA.
