Question

The temperature of a substance increases by \(27^{\circ} \mathrm{C}\) What is the value of this increase of Kelvin scale? (A) \(300 \mathrm{~K}\) (B) \(2-46 \mathrm{~K}\) (C) \(7 \mathrm{~K}\) (D) \(27 \mathrm{~K}\)

Short answer

The value of the temperature increase on the Kelvin scale is \(27 \mathrm{~K}\).

Step-by-step solution

Understand the relationship between Celsius and Kelvin scales

The Celsius and Kelvin scales have the same interval or "size" between their degrees. The difference between them is that the Kelvin scale starts at absolute zero (-273.15°C), while the Celsius scale starts at the freezing point of water (0°C).

Convert the temperature increase from Celsius to Kelvin

Since both Celsius and Kelvin scales have the same interval, a temperature change of 27°C is equal to a temperature change of 27K.

Identify the correct answer

Comparing our result with the given options, we can see that the correct answer is: (D) \(27 \mathrm{~K}\)
