Question

State whether the following is true or false

One degree rise on a Celsius scale is equal to one degree rise on a Kelvin scale.

• A. True
• B. False

Answer 1

The correct option is A True

1. The SI unit of temperature is Kelvin (K).
2. The other commonly used units are degree Celsius (${}^{0}C$) and degree Fahrenheit (${}^{0}F$).
3. There are temperature scales corresponding to each unit of temperature.
4. They are the Celsius scale, Fahrenheit scale, and kelvin scale.
5. For all these temperature scales, the lower fixed point is the freezing point of water and the upper fixed point is the boiling point of water.
6. In the Celsius scale and Kelvin scale, the region between these two temperatures is divided into 100 divisions and each division is 1${}^{0}C$ and 1 K respectively.
7. But, in the Fahrenheit scale, this region is divided into 180 divisions and each division is 1${}^{0}F$.
8. Thus one-degree rise in the Celsius scale and Kelvin scale are equal, but it is different on the Fahrenheit scale.

Thus, the given statement is true.
