Chapter 12, Problem 1FC

To determine

Which statement describes the Celsius and the Kelvin temperature scales.

Answer to Problem 1FC

The correct option is, “(e) The size of the degree on each scale is the same”.

Explanation of Solution

Description:

Consider the conversion factor for degree Celsius to Kelvin.

$1°\text{C}=273.15\text{K}$

The size of one kelvin scale is identical to the size of one Celsius degree. Hence option (a) is incorrect.

The ice point in kelvin scale is $273.15\text{K}$ while the ice point in the Celsius scale is $0°$. Hence option (b) is incorrect.

The steam point of kelvin scale is $373.15\text{K}$ while the steam point in Celsius scale is $100°$. Hence option (c) and (d) is incorrect.

In every temperature scale there are 100 divisions from the ice point to the steam point of water. Hence the size of the degree on each scale is the same. Therefore, option (e) is correct.

Conclusion:

Hence, the option (e) is correct.
