Question

two thermometers are calibrated one in degrees celsius and the other in degrees fahrenheit. at what temperature are their readings the same?

Answer 1

Both scales will read temperature at -40 degree C or - 40 degree F

Step-by-step explanation:

As we know that two temperature scales are defined as

`(T_c - 0)/(100 - 0) = (T_f - 32)/(212 - 32)`

here we know that two temperature scales will read same values

so we will have

`T_f = T_c = x`

here we have

`(x)/(100) = (x - 32)/(180)`

`1.8 x = x - 32`

`x = -40 ^o C`
