Question

On the Fahrenheit scale, water freezes at 32°. On the Celsius scale, water freezes at 0°. The formula gives the temperature in degrees Fahrenheit when the temperature in degrees Celsius is known. Find a temperature when both are the same, let in the equation and solve .

Answer 1

0

Step-by-step explanation:

Answer 2

- 40 °C = - 40 °F

Step-by-step explanation:

Fahrenheit, Kelvin and Celsius are the different scales of temperature in which temperature is measured.

The conversion of T( °C) to T(F) is shown below:

T (°F) = (T (°C) × 9/5) + 32

Thus, let the same temperature be x

So,

`x=x* (9)/(5)+32`

`x-x(9)/(5)=+32`

`-(4)/(5)x=32`

`-4x=160`

`x=-40`

Thus, the temperature at which both are same = - 40 °C = - 40 °F
