Question

By imparting heat to a body, its temperature rises by ${15}^{\circ }C$. What is the corresponding rise in temperature on kelvin scale?

Answer 1

It should be noted that rise in Celsius scale is equal to rise in Kelvin scale. This is because both the scales have 100 divisions and size of each division is same for both. Thus, if temp increased by 15 divisions on Celsius scale corresponding rise would be same on Kelvin scale.
Hence, rise in temperature on Kelvin scale is 15 K.
