Solution

Kelvin Scale of Temperature: Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all motion ceases. The kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI).

The Kelvin scale of temperature:

(a) It starts at -273° C as it's zero.

(b) This scale is also called the SI scale of temperature.

(c) The magnitude of each degree on the Kelvin scale is the same as on the centigrade scale.

(d) All temperatures on the Kelvin scale are positive.

(e) The behavior of the gases cannot be expressed below -273° C as a temperature below 273 °C is not possible.

Thus, Kelvin's temperature is always positive.
