Question

Kelivn scale of yemperature is regarded better than the celsius scale .Why

Answer 1

Answer: Zero value in kelvin scale is the temperature when the Relative vibrational motion of particles in solid stops( kinetic energy=0)

But The zero value in the scale of Celcius is depends mainly on the properties of water(freezing point/melting point etc..)

zero value on Kelvin scale depends on various properties of all substances

so,

Kelvin scale of temperature is regarded better than Celcius scale.
