The temperature of a body rises by 1°C. What is the corresponding rise on the:

(a) Fahrenheit scale

(b) Kelvin scale?

(a) 100 divisions on the Celsius scale = 180 divisions on Fahrenheit scale

1 division on Celsius scale = $\dfrac{\text{180}}{\text{100}}$ = 1.8 divisions on Fahrenheit scale

So the corresponding rise on the Fahrenheit scale = 1.8°F.

(b) 100 divisions on the Celsius scale = 100 divisions on Kelvin scale

1 division on Celsius scale = $\dfrac{\text{100}}{\text{100}}$ = 1 division on Kelvin scale

So the corresponding rise on the Kelvin scale = 1 K.
