The Kelvin scale is used.
K (Kelvin)
The ideal gas equation should be used with the Kelvin temperature scale because it is an absolute temperature scale where 0 K represents absolute zero. Using Celsius or Fahrenheit scales could lead to incorrect calculations in the ideal gas equation.
K (Kelvin)
When using the ideal gas law, the temperature measurement should be in Kelvin. This is because the ideal gas law requires an absolute temperature scale for accurate calculations, and Kelvin is an absolute temperature scale where 0 K represents absolute zero.
The ideal gas equation uses the Kelvin scale for temperature. This is because the Kelvin scale is an absolute temperature scale, where 0 K represents absolute zero—the point at which gas particles theoretically have minimal kinetic energy. Using Kelvin ensures that the calculations in the ideal gas law remain consistent and accurate, as negative temperatures would not be physically meaningful in this context.
The Rankine scale is one of the temperature scales used when an absolute temperature scale is needed. The Rankine scale is useful in calcluations of oil or gas present in an oil or gas reservoir (one of the factors in the equations is the ratio of standard temperature to formation temperature; generally add 460 to the temperature in degrees Fahrenheit to obtain degrees Rankine).
No, the ideal gas equation can be used with any temperature scale (e.g., Kelvin or Fahrenheit) as long as the proper gas constant is used in the calculations. The relationship between temperature scales can easily be accounted for in the ideal gas equation by using the appropriate conversion factors.

The Kelvin scale is used for temperature measurement because it is an absolute scale based on thermodynamics. The zero point of the Kelvin scale, 0 K, corresponds to absolute zero where molecular motion ceases. This makes Kelvin ideal for scientific calculations and comparisons.
The temperature scale that must be used in all gas laws is the Kelvin scale. This is because the Kelvin scale starts at absolute zero, which is the point where particles have minimal kinetic energy, making it the ideal scale for gas laws calculations.
The ideal gas equation will give correct values as long as the temperature is expressed in an appropriate temperature scale (such as Kelvin or Rankine) to maintain a consistent relationship with the other variables involved (pressure, volume, and number of moles). Expressing temperature in degrees Celsius or Fahrenheit will not give accurate results with the ideal gas equation.
An advantage of the Kelvin scale is that all the temperatures on this scale are positive. Another advantage is that the temperature in Kelvin is directly proportional to the total internal energy of the substance: if you double the internal energy, you will double the temperature in Kelvin.
