What is the highest temperature?
357280
There must be a maximum. As an object gets hotter and hotter the molecules vibrate faster and faster. They clearly cannot exceed the speed of light so there must be a maximum.

If you mean hottest as most POPULAR , then it would be the search for Quantum Gravity ( i.e string theory, loop quantum gravity etc. )\n\nIf you mean hottest as in TEMPERATURE, then it would be the study of the Big Bang, presumably the hottest the universe ( or anything for that matter ) has ever been !\n\nIf you mean coolest as in most INTERESTING, then it would be Nanotechnology, with its many far reaching implications on everyday life.\n\nIf you mean coolest as in TEMPERATURE, then obviously Superconductivity ( which occurs only at very low temperatures ) is THE coolest !\n\nhope this answers your cool question ( no pun intended )

Approx. 1200 degrees F.

the normal temperature from the human body depends where the person lives , in the hot weather or in the cold weather, but the regular temperature is 36 or 37 degrees Celsius

Currently: 37°\n\nFair\n\nHigh: 40°\nLow: 31°

The surface of the Sun, called the photosphere, is at a temperature of about 5800 Kelvin/ 5 526 degree Celsius/ 9 980 Fahrenheit.\n\n\nErm guys, the lithosphere is the brittle uppermost shell of the earth, not the sun.  *just to clarify out things a bit*

Your body temperature is usually highest in the evening. It can be raised by physical activity, strong emotion, eating, heavy clothing, medications, high room temperature, and high humidity.

A sharp increase in temperature.

I think its because you skipped science at school. The answers were mostly simple and logical.\n\nHow high is up? - As high as you want. I like the reference to upness in the best answer. Good word that.\n\nThe temperature question needs rephrasing. I think you need to use absolute zero as a reference. In which case the temperature is about -231.5 degrees F. This will feel a lot more than twice as cold though, since our temperature sensors in our skin don't work that way.

Absolute Zero or around 20 K.\n\nMelting point 14.01 K  (−259.14 °C, −434.45 °F) \nBoiling point 20.28 K  (−252.87 °C, −423.17 °F)

About 72 degrees. This answer was gotten by averaging the monthly temperatures in the table below.

This is my guess:\n\nThe hottest temperature is probably when the particles move at almost the speed of light, I don't know what that is though.\n\nTemperatures can be as high as billions of degrees.\n\nHowever, temperature don't necessarily mean how hot it is, at temperatures of billions of degrees, you could still freeze!

On September 13, 1922, El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius)! Death Valley in California makes for a close second, though. On July 10, 1913, it got up to 134 Fahrenheit. Whew. That is HOT. Best,

The theoretical maximum temperature is also called the Planck temperature, and it was the temperature of the Universe at the instant of its creation in the Big Bang.  This temperature is 1.42 x 10^32 K.\n\nBy comparison, the Sun's corona is at a temperature of 5 million Kelvins, and the maximum temperature at the core is 13.6 million Kelvins.  Nuclear fusion occurs at the core, so temperatures of 100 million Celsius (approximately the same as Kelvin at this scale) would not be required for fusion.  However, the pressure at the center of the Sun is incredibly high.  At lower pressures, higher temperatures would be required to achieve fusion.

Many believe that it is Death Valley in California. True enough on many days. But El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured. In Death Valley, it got up to 134 Fahrenheit on July 10, 1913. \n\nThe coldest temperature ever measured on Earth was -129 Fahrenheit (-89 Celsius) at Vostok, Antarctica, on July 21, 1983.

The biggest scorcher ever noted was on September 13, 1922, in El Azizia (also known as Al 'Aziziyah), Libya, when the mercury hit 136 degrees Fahrenheit. El Azizia is near the Sahara desert, so it's no wonder the place gets so hot. Temperatures have likely gotten even hotter in the actual desert, but weather stations aren't there to record it.

u can't have water upto 40 below zero!!!\nthe lowest temp(in centigrade) u can reach is -12 c \nthis is achieved by a process called super cooling\nin this the temp of the surroundings is controlled, and care is taken that the surface of the water is not disturbed\nsimilarly u can super heat water upto 137 c
