Question

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

(a) Fahrenheit scale 

(b) Kelvin scale?

Answer 1

(a) Since 100 divisions on Celsius scale =180 divisions on the Fahrenheit scale 1 division on Celsius scale 

∴ 1 division on Celsius scale 

= 1.80 / 1.00 × 1 

= 1.8 divisions in the Fahrenheit scale. 

For 1°C rise corresponding rise in Fahrenheit = 1.8°F 

(b) Since 100 divisions in the Celsius scale = 100 divisions in the Kelvin scale 

1 division on Celsius scale = 100 / 100 × 1

= 1 division on Kelvin scale 

For 1°C rise corresponding rise in Kelvin is 1 K.
