Correct option is D)

Suppose, C1 is Celsius scale is equal to F1 in Fahrenheit scale and C2 is Celsius scale is equal to F2 in Fahrenheit scale. So using the conversion formula we can get,

ΔC=95×ΔF ; where ΔC=C1−C2 and ΔF=F1−F2

Using this formula, 40∘ rise in temperature on Celsius scale is equal to 72oF increase on Fahrenheit scale.

Explanation:

I hope it's help you

To find the answer, we have to convert the Fahrenheit scale to the Celsius scale.

Temperature in Fahrenheit, °F = 36

Temperature in Celsius, °C = (F - 32)×(5/9)

= (36 - 32)×(5/9)

= 4×(5/9)

= 20/9

≈ 2.2

The rise in temperature on the Celsius scale is 2.2 ° C approximately.
