The introduction of Kelvin scale in thermodynamic is according to_______________?
Correct answer: B. Charles law
- A. Boyles law
- B. Charles law
- C. Daltons law
- D. Grahams law
Explanation
Charles's law states that the volume of a fixed mass of gas is directly proportional to its absolute temperature at constant pressure, V/T = constant. This relationship requires temperature to be measured from absolute zero, so it led to the Kelvin thermodynamic scale. Students may choose a because Boyle's law is another fundamental gas law, but Boyle's law relates pressure and volume at constant temperature.

About Charles's Law
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. Questions involve the Kelvin scale, the equation V₁/T₁ = V₂/T₂, volume-temperature graphs, and the need to distinguish Charles's law from Boyle's law, which relates pressure and volume.
