Temperature is the intensity of heat or coldness in a substance, object or environment. In the United States this is measured with a scale known as Fahrenheit that was historically common in other countries until the post WWII era when all other major nations switched to a scale called Celsius that is arguably more intuitive because it places the freezing point of water at 0°C and the boiling point at 100°C. The following are examples of notable or interesting temperatures.
Temperature | Fahrenheit ( °F ) | Celsius ( °C ) | Absolute zero | -459.67°F | -273.15°C | Surface of Pluto | -375°F | -225°C | Surface of Neptune | -330°F | -200°C | Surface of Uranus | -320°F | -195°C | Surface of Saturn | -220°F | -140°C | Surface of Jupiter | -166°F | -110°C | Lowest temperature on Earth recorded July 21, 1983 at Vostok, Antarctica | -128.6°F | -89.2°C | Surface of Mars | -85°F | -65°C | Point at which Celsius and Fahrenheit are the same | -40°F | -40°C | Freezing point of sea water | 28.4°F | -2°C | Freezing point of water | 32°F | 0°C | Average surface temperature on Earth | 59°F | 15°C | Room temperature | 68°F | 20°C | Normal body temperature | 98.6°F | 37°C | Hottest temperature on Earth recorded July 7, 1913 at Furnace Creek Ranch, CA, USA | -128.6°F | 56.7°C | Boiling point of water | 134°F | 100°C | Surface of Mercury | 333°F | 167°C | Surface of Venus | 867°F | 464°C | Melting point of gold | 1945°F | 1063°C | Melting point of iron | 2200°F | 1204°C | Melting point of carbon | 6,422°F | 3,550°C | Surface of Sun | 10,000°F | 5,537°C | Temperature of Lightning (max approx) | 50,000°F | 27,760°C | Core of the Sun (approx) | 27 million °F | 15 million °C |
Carbon has the highest melting point of any element at 6,422°F. Helium has the lowest melting point at -458°F. The surface of the Sun is not as hot as the Sun's outer atmosphere known as the corona that reaches about 2 million °F. The core of the Sun is the hottest thing in the Solar System. According to NASA, the energy released by the Sun in one second is approximately equivalent to 1.5 million times the annual energy consumption of all humans.
