WebThat's negative 72 plus 32. So the temperature in Fahrenheit would equal negative 40 as well. So negative 40 degrees Celsius is the same thing as saying negative 40 degrees Fahrenheit. That's kind of just a fun fact. And another observation from this little factoid is that Celsius and Fahrenheit scales can both have negative or positive values. WebSep 10, 2016 · molar mass = -182.855. So when I am doing delta t, its supposed to be final minus initial right? So I am doing the new temperature, 4.1, degrees as the final, and the unchanged or natural temperature, 5.5, as the initial. The answer would be the same thing just positive, but I am probably doing something wrong to have this negative answer.
