Question

4) Which of the following temperature will read the same value on Celsius and Fahrenheit scales? * 1) -40 degree Celsius 2) +40 degree Celsius 3) -80 degree Celsius 4) -20 degree Celsius​

Answer 1

Explanation:

C-0/100 = F-32/180

C/100 = C-32/180

180C = 100C - 3200

180C-100C = -3200

80C = -3200

C = -3200/80

C =
