For which of the following pairs of temperature scales is the size of a degree identical?

Options

  1. ACelsius scale and mercury scale
  2. BCelsius scale and ideal gas scale
  3. CIdeal gas scale and absolute scale
  4. DMercury scale and ideal gas scale

Correct answer

C. Ideal gas scale and absolute scale

Step-by-step solution

The size of a degree on the Celsius scale is defined to be exactly equal to the size of a degree on the absolute (Kelvin) scale. A temperature difference of 1^ C is equivalent to a temperature difference of 1 K . The ideal gas temperature scale is based on the properties of an ideal gas and is theoretically identical to the absolute thermodynamic temperature scale (Kelvin scale). Therefore, the size of a degree on the ideal gas scale is identical to that on the absolute scale. Since the Celsius, ideal gas, and abso
