Which of the following is true regarding temperature scales

Which of the following is true regarding temperature scales? Celsius and Farenheit are examples of thermodynamic temperature scales. The Kelvin scale relies on only one calibration point, other than absolute zero When inserting temperatures into the ideal gas law, they may be in either the Celsius or Kelvin scale. A unit change on the Celsius scale is the same as a unit change on the Rankine scale.

Solution

there are three temprature scale

1 celsius

2 kelvin

3 fahrenheit

so first option is correct.

second is wrong because kelvin has two calibration point one is absolute zero and another is triple point of water

third is wrong because im ideal gas law tempratue is always in kelvin

fourth is also wrong because unit change in both is not same
