Question

The rise in temperature of 1K is equal to a rise in temperature of $1°\mathrm{C}$

• A. True
• B. False

Answer 1

The correct option is A True

The rise in temperature of 1K is equal to a rise in $1°\mathrm{C}$ because the degree of divisions is the same on both scales.

The scales of temperatures were stabilized in regards to the melting and boiling points of water because water is present everywhere and is also a universal solvent.

In the Kelvin scale, the lower point is 273.15K which is the melting point of water and the higher point is the 373.15K which is the boiling point of the water.

$$\begin{gathered} \mathrm{Total}\mathrm{no}\mathrm{of}\mathrm{divisions}=373.15-273.15 \\ =100 \end{gathered}$$

In the Celcius scale, the lower point is $0°\mathrm{C}$ which is the melting point of water and the higher point is $100°\mathrm{C}$ which are the boiling point of the water.

$$\begin{gathered} \mathrm{Total}\mathrm{no}\mathrm{of}\mathrm{divisions}=100-0 \\ 100 \end{gathered}$$

As we can see in both the temperature scales the total no. of divisions is 100 which is equal and either for kelvin or for Celcius the change will be the same.
