| 1. | The Kelvin scale is defined on the basis of the second law of thermodynamics.
|
| 2. | Hence, the Kelvin scale is a ratio scale.
|
| 3. | The entire "'scientific community "'measures "'temperature "'using the Celsius scale, and thermodynamic temperature using the Kelvin scale.
|
| 4. | The coldest temperature possible on the Kelvin scale is 0 ( the temperature at which all molecular activity ceases ).
|
| 5. | An exceptionally suitable system is the ideal gas, which can provide a temperature scale that matches the absolute Kelvin scale.
|
| 6. | It is minus 273.15 degrees on the Celsius scale, minus 459.67 on the Fahrenheit scale and zero on the Kelvin scale.
|
| 7. | Celsius temperature is measured on an interval scale, whereas the Kelvin scale has a true zero and so is a ratio scale.
|
| 8. | It uses the Kelvin scale for measurement and selects the triple point of water at 273.16 K as the fundamental fixing point.
|
| 9. | A system with a truly negative temperature on the Kelvin scale is " hotter " than any system with a positive temperature.
|
| 10. | It is minus 273 . 15 degrees on the Celsius scale, minus 459 . 67 on the Fahrenheit scale and zero on the Kelvin scale.
