Question
Why is kelvin scale of temperature regarded better than centigrade scale?
Solution
The kelvin scale of temperature regarded better than centigrade because it has an only positive value of temperature. We do not have any temperature below zero degrees. But on the centigrade scale of temperature, there can be positive as well as negative temperatures. Further, many equations and relationship (such as Charle’s law) can be written in a much simpler form in terms of kelvin scale (also called Thermodynamic scale of temperature) than in centigrade (or celsius) scale.
