At what temperature is the Fahrenheit scale reading equal to (a) twice (b) half of the Celsius?
Step 1: Formula used
TC=TF-32×59
Step 2: Calculation
(a) Put TF=2TC
TC=2TC-32×599TC=10TC-160
Hence TC=160°C
(b) Put TF=TC2
TC=TC2-32×59
TC=5TC18-160913Tc=-320Tc=-24.61°C
Hence, the temperature is Tc=-24.61°C.
