Question

1 degree rise on celsius scale is equal to _____ degree rise on fahrenheit scale.

• A. 1
• B. 1.8
• C. 0.56
• D. 10

Answer 1

The correct option is B

1.8

We know, $F=1.8C+32$

Then, for water:
Freezing point - 0 degree celsius = 32 degree fahrenheit

Boiling point - 100 degree celsius = 212 degree on fahrenheit.

Therefore, 180 degree rise on fahrenheit scale is equal to 100 degree rise on celsius scale. We see, 1.8 degree rise on fahrenheit scale is equal to 1 degree rise on celsius scale.
