Absolute Zero
Chat with our AI personalities
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.
At absolute zero temperature, the volume of an ideal gas would theoretically be zero.
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.
Standard conditions, or standard temperature and pressure (STP) is the atmospheric pressure at sea level with temperature at zero degrees Celsius (273.15 Kelvin).
The term defined as the atmospheric pressure at sea level at zero degrees Celsius is standard atmospheric pressure, which is typically defined as 101.325 kilopascals or 1 atmosphere.
The thermodynamic temperature scale, also known as the Kelvin scale, is an absolute temperature scale where zero is the point at which all thermal motion ceases (absolute zero). It is defined based on the properties of ideal gases and is commonly used in scientific and engineering applications. The Kelvin scale is related to the Celsius scale by the equation: T(K) = T(°C) + 273.15.
