Concepts Of Physics MCQ Edition [Volume 2]PhysicsHeat and Temperature
For which of the following pairs of temperature scales is the size of a degree identical?
Options
- ACelsius scale and mercury scale
- BCelsius scale and ideal gas scale
- CIdeal gas scale and absolute scale
- 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
