Answer to Question #143333 in General Chemistry for Andy

Question

At what temperature have the Celsius and Fahrenheit readings the same value

Answer 1

We have 

Tf = 9/5 Tc +32 

where Tf is temperature in fahrenheit and Tc in degree celsius

when

Tf = Tc

Tf = 9/5 Tf +32 

-4/5 Tf = 32

Tf = -40 F

Tc = -40 C

Answer

At −40 oC
