Question

at what temperature will the centigrade thermometer read twice as much as Fahrenheit thermometer​

Answer 1

Answer:

The point at which the temperature in Fahrenheit is exactly twice that in Celsius is 320° Fahrenheit, which is equal to 160° Celsius.

Answer 2

The temperature at which the centigrade thermometer read twice as much as the Fahrenheit thermometer​ is 320°.

• The conversion formula for converting Fahrenheit into Centigrade is :

        F = 9/5C + 32                                eq(1)

• According to the requirements, F = 2C.

• Now, Substituting F in eq(1), we get,

        2C = 9/5C + 32

• Now, Subtracting 9/5C from both sides

        2C - 9/5C = 9/5C + 32 - 9/5C

        2C - 9/5C = 32

        10/5C - 9/5C = 32

        1/5C = 32

        C = 160°

• Therefore, F = 2C

                             = 2(160°)

                             = 320°
