Question

Which of the following comparisons is false? 5° c is warmer than 5°f. 15° c is cooler than 60° f. 30° c is warmer than 90° f. 35° c is cooler than 100° f.

Answer 1

Answer:

Step-by-step explanation:

To compare celsius and Fahrenheit temperatures, we have to convert one unit to another.

The conversion formula is

$F=\frac{9C}{5} +32$

Using this let us compare one by one.

$F=\frac{9*5}{5} +32=41$

Hence C is not warmer than F

ii) $F=\frac{9*15}{5} +32=59$

Hence C is coller than F.

ii) $F=\frac{9*30}{5} +32=86$

N0t warmer than 100 degrees

iv) $F=\frac{9*35}{5} +32=99$

Hence not warmer than 100 F

So only correct option is option C

Answer 2

30° Celsius is not warmer than 90° Fahrenheit. You can find this by doing the conversion of 30° Celsius to Fahrenheit. This is 86° Fahrenheit. Obviously, 86 is not more than 90, so it is false, meaning it is the correct answer.
