Temp facts & stats

Question 1

At what temperature does pure water freeze at sea level, in degrees Celsius?

Accepted Answer

0°C. The Celsius scale sets water's freezing point at 0°C and boiling point at 100°C at sea-level pressure.

Question 2

At what temperature does pure water freeze on the Fahrenheit scale?

Accepted Answer

32°F. Water freezes at 32°F, which equals 0°C.

Question 3

At what temperature do the Celsius and Fahrenheit scales show the same number?

Accepted Answer

-40. The two scales cross at -40, so -40°C is exactly -40°F.

Question 4

At what temperature does pure water boil at sea level, in degrees Fahrenheit?

Accepted Answer

212°F. Water boils at 212°F at sea level, which equals 100°C.

Question 5

Normal human body temperature is roughly what?

Accepted Answer

37°C (98.6°F). Typical body temperature is around 37°C, though it varies a little between people and through the day.

Question 6

On Anders Celsius's original 1742 scale, water boiled at which value?

Accepted Answer

0. Celsius's original scale ran backward, with 0 for boiling and 100 for freezing; it was flipped soon after.

Question 7

At the level of atoms and molecules, what does temperature measure?

Accepted Answer

The average kinetic energy of the particles. Temperature reflects how fast particles move on average, their average kinetic energy.
