What is the temperature which has the same value in Celsius and in Fahrenheit scales?

Text Solution

Verified by Experts

Let the temperature be x degree. As per the question C = F = x
From the relation for equivalence of temperature scales, we know `C/5=(F-32)/9`.
`therefore " " x/5=(x-32)/9` or, 9x = 5x-160
or, 4x = -160 `therefore` x = -40
`therefore " " -40^(@)C=-40^(@)F`
