Question

Explain why Kelvin temperature is used only in studying gas laws?

Answer 1

1. Charles law can be stated as, for a fixed mass of gas, the volume of gas (v) is directly proportional to the absolute temperature (T)
2. V &T (Pressure is constant) $\frac{V}{T}=K$ (K is the proportionally constant)
3. The kelvin scale must be used because zero on the kelvin scale corresponds to a complete stop of molecules motion.
4. The pressure and Volume of gas depends on the kinetic energy or motion of the particles.
5. kelvin scale is an absolute related to kinetic energy and volume.

That is why kelvin temperature is used only in studying gas law.
