Question

8. TEMPERATURE To convert a temperature in degrees Celsius to degrees

Fahrenheit, multiply the Celsius temperature by and then add 32°. Is a
temperature in degrees Celsius proportional to its equivalent
temperature in degrees Fahrenheit? Explain your reasoning. Proportional or Nonproportional

Answer 1

A temperature in degree Celcius is not equivalent temperature in degrees Fahrenheit. So, NOT proportional.

This is the formula:

`F=(9)/(5) C+32`

F increases as C increases and F decreases as C decreases, but the relation is not direct proportionality.

If the formula had been

`F=(9)/(5) C`

it would have been a direct proportion.

However, the addition of the +32 makes the formula no longer a direct proportion.

Hope you understand a bit more now!
