Question

all temperature in kelvin scale are in positive figure

Answer 1

There is no negative number on Kelvin scale.

On Kelvin scale the temperature is set at -273.15 when it is absolute zero, beyond which the temperatures cannot go.

Thus, the scale unlike others starts at zero which is the lowest temperature on the scale.

 As lowest value on the Kelvin scale is zero, hence all figures are in positive value.

Answer 2

Answer:

Explanation:

The least temperature on the Kelvin scale is 0. This is equal to -273°C.

At this temperature, it is assumed that the volume of any gas is 0. Which is not physically or Chemically possible.

Hence all temperature in kelvin scale are in positive figure.
