In the relationship ΔP ∝ ΔT ,what scale is used for temperature?
A)Fahrenheit
B)Celsius
C)Kelvin
D)Both Celsius and Kelvin may be used since the degree size is the same for both.

The relationship ΔP ∝ ΔT is based on the ideal gas law, which states that pressure and volume are directly proportional to temperature, assuming constant number of particles and constant volume, respectively. The Kelvin scale is used in the ideal gas law because it has an absolute zero point, which makes it possible to express temperature as a positive number without using negative signs. Furthermore, Kelvin has the same size of degree as Celsius, so both scales may be used interchangeably without affecting the proportionality relationship. Therefore, the best choice for the relationship ΔP ∝ ΔT is the Kelvin scale (choice C).
