The difference in temperature between two bodies is 30 degree centigrade. What is the difference in degree Fahrenheit?
Answer & explanation
Correct answer: option 2
The correct answer is option 2. 54.
To convert from degrees Celsius to degrees Fahrenheit, you can use the formula:
\[ F = \frac{9}{5}C + 32 \]
Given that the difference in temperature between two bodies is 30 degrees Celsius, we can find the difference in degrees Fahrenheit by multiplying 30 by \( \frac{9}{5} \) and then adding 32.
\[ \Delta F = \frac{9}{5} \times 30 = 54 \]
So, the difference in degrees Fahrenheit is 54.
Therefore, the correct answer is 54.
