Chapter 24, Problem 32A

To determine

To Explain: Difference between Kelvin and Celsius in an oven and a star.

Explanation of Solution

Introduction:

Kelvin and degree Celsius are unit of the temperature.

Relation between Kelvins and degree Celsius:

  $T\left(\text{in K}\right)=T\left({\text{in }}^{\text{o}}\text{C}\right)+273.15$

In case of over, if the unit is in the degree Celsius then the temperature is ${600}^{\circ }\text{C}$ or $873.15\text{ K}$ and if the unit is Kelvin then the temperature is $600\text{ K}$ or ${326.85}^{\circ }\text{C}$ . So, temperature in degree Celsius is hotter than temperature in Kelvin by $45\%$ .

Similarly, In case of star, if the unit is in the degree Celsius then the temperature is ${60000}^{\circ }\text{C}$ or $60273.15\text{ K}$ and if the unit is Kelvin then the temperature is $60000\text{ K}$ or ${59726.85}^{\circ }\text{C}$ . So, temperature in degree Celsius is hotter than temperature in Kelvin by $0.45\%$ .

Conclusion:

Hence, in case of star it is not a big difference but in case of oven it makes a huge difference.
