Question

A Fahrenheit thermometer reads 104°F while a faulty celcius thermometer reads 41°C the correction to be applied to the celcius thermometer is

Answer 1

Correction to be applied on the thermometer.

Formula for converting a Fahrenheit temperature into Celsius temperature is :-

$T^{\circ} _ {C} = ( T^{\circ}_{F} -32) * 5/9$

Now, in the question it is given that the Celsius Thermometer is faulty.

We are given the correct reading of the Fahrenheit thermometer.

Let us use the formula above to convert it into Celsius.

$T^{\circ}_{C} = ( T^{\circ}_{F} -32) * 5/9\\ = (104 -32) * 5/9\\ = 72 * 5/9\\ = 40^{\circ} C$

Faulty thermometer gave the reading of 41°C, whereas the reading should have been 40°C.

Error was by 1°.

Answer 2

-1°C  correction to be applied to the Celsius thermometer

Explanation:

Fahrenheit thermometer reads 104°F

We know that

F  = 9C/5  + 32

=>  104 = 9C/5 + 32

=> 72 = 9C/5

=> 8  = C/5

=> C = 40

104°F  = 40°C

Actual temperature = 40°C

faulty celsius thermometer reads 41°C

Hence correction of  -1°C   need to be applied  so that celsius temperature is correct
