SUMMARY
The ideal gas law, represented by the equation PV = NkT, requires the use of absolute temperature measured in Kelvin to ensure accurate calculations. Using the Celsius scale leads to nonsensical results because it allows for negative temperature values, which do not correspond to physical states of matter. At 0°C, the pressure of an ideal gas is not zero; it only reaches zero at absolute zero, defined as 0K. Therefore, absolute temperature is essential for the proper application of the ideal gas law.
