Question

At what temperature will be the reading on the fahrenheit scale be double of that on the Celsius scale.

(please provide the working...)​

Answer 1

Answer:

at  160degree celsius

Explanation: we know that the relationship b between celsius and fehenert scale is

t° c = (9/5 t +32)°F

so for reading to be double on fehrenheit  scale

2 t° c  = (9/5t +32)°F

or (2-9/5) t = 32

or 1/5 t =32

or t = 32*5 =  160
