Or, to put it another way, freezing-point is 274 absolute temperature.
In his article on Heat Thomson gave two definitions of the scale of absolute temperature.
It is that emission grows as the fourth power of absolute temperature.
That is, the pressure of a gas varies directly as its absolute temperature, if the volume is kept constant.
absolute temperature is without influence, provided every trace of air or foreign gas be got rid of.
At a constant pressure the volume of a given mass of gas is proportional to its absolute temperature.
At the absolute temperature T, if the pressure be unaltered, the volume of this gas will be VoT / 273.
This scale, proposed by Sir W. Thomson in 1848, is called the "scale of absolute temperature."
In order to determine this, the absolute temperature of the steam at admission and exhaust pressures must be known.
The absolute temperature is obtained by adding 461 to the reading in degrees Fahrenheit (F.).
absolute temperature n.
Abbr. T
Temperature measured in kelvin from absolute zero.
absolute temperature scale A temperature scale having absolute zero as the lowest temperature. Absolute temperature scales only have positive numbers. The Kelvin scale and the Rankine scale are absolute temperature scales. Compare relative temperature scale. |
