Question

The temperature of a body rises by 4 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.

(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.
