Gas Thermometer
The establishment of the International Temperature Scale has required that the thermodynamic temperatures of the fixed points be determined with as much accuracy as possible. For this purpose a device was needed that measures essentially the thcmodynamic temperature and does not depend on any particular thcrmomctric substance. On the other hand, since it was needed only for a few highly accurate measurements, it did not need to have the convenience o f such instruments as resistance thermometers, mercury thermometers, and thermocouples. The dcvicc that has filled this need is the gas thermometer.

1. More than a century ago scientists noticed the dependence between the temperature and the volume of a gas. 2. The temperature at which the volume of the gas sample would become zero was named the absolute zero. 3. Hie scale according to which the absolute zero is taken to be 0° is the International Standard temperature scale. 4. The triple point of water is the temperature when vapourization begins. 5. The temperature by the Kelvin scale is the temperature by Celsius scale plus 273.15°. 6. Gas thermometer is used for ordinary measurements. 7. Gas thermometer is a convenient instrument. 8. This dcvicc is highly accurate.
