Conversion on chemistry

Question

which of the following is the coldest temprature 40 C or 40 F?

Answer 1

Hello Dyana,

The easiest way to figure this out is to convert the temperatures so they are in the same units.

 

The formula for conversion between Celsius and Fahrenheit is: T(°F) = (T(°C) *1.8) + 32

 

So, if we convert 40°C to Fahrenheit, we get: T(°F) = (40*1.8) + 32 = 72+32 = 104°F 

 

So,  40°C = 104°F        *** 40°F is colder than 40°C ***

 

We can look at it the other way too, from Farenheit to Celsius:  T(°C) = (T(°F) - 32)/1.8

 

So, if we convert 40°F to Celsius, we get: T(°C) = (40 -32)/1.8 = 8/1.8 = 4.44°C

 

So, 40°F = 4.44°C  *** 40°F is colder than 40°C***

 

Same answer, different ways of solving the problem.
