fascinating range

Stove (while being used): 200°C to 300°C when in use.

Core of the Earth: In general, temperatures range from about 4,400°C (7,952°F) to about 6,000°C (10,800°F)

Surface of the Sun: approximately 5,500°C (9,800°F)

Core of the Sun: The Sun’s core is where nuclear fusion occurs, converting hydrogen into helium. The temperature at the Sun’s core is an astonishing 27 million°C (15 million°F) It’s the hottest part of our solar system.

Random Examples:

  • Lightning Bolt: A lightning bolt can reach temperatures of 30,000°C (54,000°F) during discharge.
  • Lava Flow: Molten lava from a volcanic eruption can range from 700°C to 1,200°C (1,292°F to 2,192°F).
  • Spacecraft Reentry: During reentry into Earth’s atmosphere, spacecraft experience temperatures of about 1,650°C (3,002°F).
  • Boiling Water: Boiling water on your stove reaches 100°C (212°F) at sea level.
  • Liquid Nitrogen: Liquid nitrogen, used in cryogenics, is extremely cold at around -196°C (-321°F).
  • Absolute Zero: The theoretical lowest temperature, known as absolute zero, is -273.15°C (-459.67°F).

27million°C is only 15million°F???

Fahrenheit is a weird system

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

I don't know there was some conversion from celsius to farenheit like (9/5)*(°C) + a number

So farenheit should be bigger than celsius for millions afaik. Maybe the poster was mistaken?

I tried to convert online and this was the result: 48600030(48million)

They got the units mixed up but the numbers are right, based on OP’s graphic.

What do you cook at 300C in your stove ? That seems more a ‘burn everything’ temperature than ‘my meal is cooked’ temperature.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

some cookies, pastry, etc. Small food objects usually require higher temps to cook better, while bigger ones like pizza are best cooked at a bit lower temps. Dont remember exactly why because I didnt like the subject lol

tbf, by earthly standards the surface of the sun is insanely hot

[–] [email protected] 11 points 1 year ago

Yep. By human standards even the surface of a stove (in operation) is insanely hot.

Lightning gets there.

[–] [email protected] 2 points 1 year ago (2 children)

isn't the surface of the sun hotter than the core or am I misremembering ?

[–] [email protected] 4 points 1 year ago (1 children)

You're probably thinking of the corona being hotter then the surface. It's odd because the corona is farther away from the center, and I think it is still unexplained as of today

[–] [email protected] 2 points 1 year ago

ah yeah thats what I was thinking about sorry

[–] [email protected] 3 points 1 year ago

The sun’s core can reach 27 million degrees F (15 million C), and the surface temperature can reach only about 10,000 degrees F (5500 degrees C), but as Hexagon replied, the sun’s corona, which is above the surface, can also reach several million degrees as well.

Can't use metric
