Question

The melting point of ice on the Celsius and Kelvin scales, respectively is:

• A. ${373}^{0}Cand273K$
• B. $0^{0}Cand273K$
• C. ${273}^{0}Cand373K$
• D. ${100}^{0}Cand373K$

Answer 1

The correct option is B

$0^{0}Cand273K$

The relation between Celsius and Kelvin scale is given by the formula:

$$\begin{gathered} K={}^{0}C+273 \\ {}^{0}C=K-273 \end{gathered}$$

• The melting point of ice on the Celsius scale is $0^{0}C$
• The melting point is usually defined as the point at which materials change from a solid to a liquid.

Using the above formula, the melting point of ice on the Kelvin scale is $0^{0}C+273=273K$.

Therefore, Option B is correct.
