Question

Which is colder, 0°C or 20°F?

Answer 1

0°C is colder than 20°F.

Step-by-step explanation:

0°C is colder than 20°F.

On the Celsius scale, the freezing point of water is 0°C and the boiling point is 100°C. On the Fahrenheit scale, the freezing point of water is 32°F and the boiling point is 212°F. Since 0°C is below the freezing point of water on both scales, it is colder than 20°F.

Therefore, 0°C is colder than 20°F.

Answer 2

In order to compare the two temperatures, we need to convert 20°F into Celsius. The formula we need to use is:

`T(^(\circ)C)=(5)/(9)(T(^(\circ)F)-32)`

Substituting 20°F, we find

`T(^(\circ)C)=(5)/(9)(20^(\circ)F-32) =-6.7^(\circ)C`

And this is less than 0°C, so the answer is

20°F is colder than 0°C.
