6000 K (aprox 6000 ºC)\nThese are actual measurements. You don´t need to put a termometer or to actually GO there to know that. \nThere are other ways, typically involving light spectrum analysis, to accurately measure that.

You might not have intended it, but your question is a lot more complex than you might have thought.  It turns out that the temperature of the sun is a function of how deep into the sun you are, with the surface temperature being about 6000 Kelvins.  To make things even more complicated, the Corona of the sun (which extends in all directions around the sun beyond the surface) is actually 1,000,000 Kelvins.\n\nThis fact is well established, but further research is required to understand *why* there is such a huge difference in temperature between the two.\n\nNow for the second part of your question:\n\nThe light intensity of the sun drops off as the inverse square of your distance from the sun.  The "heat" is another thing entirely, because heat is defined as the average kinetic energy of particles, and photons don't count strictly in that definition.\n\nThere are particles that come from the sun in the form of solar wind, and around the region of the Earth, they have a "temperature" around 1000k.

The sun and lightning may seem to be equal, but it appears that lightning is 5 times hotter than the sun. The sun's surface is 1,000°F. Times that by 5, and you have the temp of a lightning bolt.

How hot is concentrated light, what is the temp of the sun?\n\nWELL WE HAVE A ENERGY SHORTAGE, ONLY AT SUNSET.\n\n I read about Solar collection in power plants like Solar One.  In these plants the where they make molten salt, for heat transfer for running steam generator. At the reciever of Solar One plant or concentrated light point temperature reachest approximately 1,050 Fahrenheit.\n    \n      THIS LINK IS ABOUT YOUR SUN AND THE TEMPS ARE HOT.\n         SO HOW MUCH LIGHT CAN WE CONDENTRATE MORE  \n           DEVELOPMENT IN SOLAR SAILS\n\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html \n\n Earth's Sun is a medium-sized star which lies on the main sequence with 90% of the known stars. It has a effective surface temperature is 5780 K, putting it in spectral class G2. Its mass is 1.989 x 1030 kg and its mean radius is 6.96 x 108 meters. The mass of the sun is over 99.8% of the mass of the entire known solar system, leading de Pater and Lissauer to refer lightly to the solar system as "the Sun plus some debris". \n\nThe sun radiates energy at the rate of 3.85 x1026 watts. Just outside the earth's atmosphere solar energy is received, assuming normal incidence, at the rate of 1340 watts per square meter. \n \n\nThe orbit of Earth ranges from 1.47 to 1.52 x 1011 meters from the Sun. The average light travel time to the earth is 8.3 minutes. \n\nThe radius of the sun at 696,000 km is 109 times the Earth's radius. Its surface gravity is 274 m/s2 or 28.0 times that of the Earth. Its mean density is 1410 kg/m3 or 0.255 times the mean density of Earth. \n\nThe composition of the sun is 71% hydrogen, 27.1% helium and less than 2% of all other elements. \n\nThe center temperature is modeled to be 15.5 million K. The Sun is fueled by the proton cycle of nuclear fusion.\n\nEscape velocity = 618 km/s\n\nSO

Venus is the hottest planet, with the maximum surface temp. of 900 degrees F.\nreason\nthe component of the atmosphere is carbon dioxide, which traps heat in a greenhouse effect far stronger that that of the earth.\n\nmercury has a max temp of 800 in sunlight and -270 on the dark side\n reason. sudden changes of temp is caused by the planets atmosphere is almost nonexistent. it consists only of minute amounts of helium and hydrogen

On the vernal equinox, the sun is directly overhead the Earth's equator at local noon, and we are told that the insolation under those conditions is 1368 W/m^2.\n\nAt latitudes other than the equator, the solar energy per unit area is decreased by a factor of cos(L), where L is the latitude.  This is called the "projection effect".  At 40 degrees latitude, the incoming solar energy per unit area is therefore:\n\n1368 W/m^2 * cos(40 deg) = 1368 W/m^2 * 0.766 = 1048 W/m^2.\n\nI'm assuming the question is asking how long it would take to bring the water to a boil, not how long it would take to completely boil away the water.\n\nIn either case, you are missing a key bit of information necessary to answer the question:  the initial temperature of the water.  Let's assume that temperature is T.  I'll also assume that you are located as sea level, so the boiling point of the water is 100 C.\n\nThe specific heat capacity of water is 4.1855 J/(g*degC), and the density of water is ~1.00 gm/cm^3, so to bring one liter of water from temperature T to 100 C requires:\n\nE = 4.1855 J/(g*degC) * 1000 cm^3 * 1 gm/cm^3 * (100 degC - T) \nE = 4.1855*10^3 J/degC  * (100 degC - T)\n\nWe have a collector with a 1 m^2 surface area, so it supplies 1048 W = 1048 J/sec at 40 degrees latitude, all of which we are to assume goes into heating the water.\n\nWith these assumptions, it would take:\n\nt = [4.1855*10^3 J/degC  * (100 degC - T)]/(1048 J/sec)\n\nseconds to bring the water to a boil.\n\nFor instance, if T = 25 C, t = 299.54 sec ~= 5 minutes to bring the water to a boil.

You do not possibly have enough information to answer this question properly, you need to know, where it is at, how far from the sun, like the others said, is there a planet or any obstacle between it and the sun, what is it's current temp, so on and so on....here is something about tempature in space though\n\nEmpty space itself cannot have a temperature, unless you mean some abstruse question about quantum vacuums.\n\nHowever, if you put a physical object into space, it will reach a temperature that depends on how efficiently it absorbs and emits radiation and on what heating sources are nearby.  For example, an object that both absorbs and emits perfectly, put at the Earth's distance from the Sun, will reach a temperature of about 280 K or 7 C. If it is shielded from the Sun but exposed to interplanetary and interstellar radiation, it reaches about 5 K.  If it were far from all stars and galaxies, it would come into librium with the microwave background at about 2.7 K. Spacecraft (and spacewalking astronauts) often run a bit hotter than 280 K because they generate internal energy.

The sun is radiating heat which is absorbed by your body and clothes.  The body tries to maintain a consistent internal temperature of around 98.6 degrees.  As your body and clothes absorb heat energy from the sun, your body will attempt to compensate for this additional heat by causing your skin to perspire.  As the perspiration evaporates off of your skin, it carries away some of the heat from your body, thus lowering your body temperature.

Venus is the brightest object in our sky, after the sun and moon. Swirling clouds of sulphuric acid obscure Venus’s surface and inhibited study of the planet from earth until technology permitted space vehicles, outfitted with probes, to visit it. The probes determined that Venus is the hottest of the planets, with a surface temperature of about 462° C (864° F). Scientists believe a greenhouse effect causes the extreme temperature, the planet’s thick clouds and dense atmosphere trapping energy from the sun. So, Venus Have a high surface temperature.

well...obviously it's kelvin!\n\nand i think they meant -345.388 degrees fahrenheit.  there's a little difference there....like about 700 degrees!

hearts  300 kelvin\n\nstars (surface) 2,500 and 40,000°C.  Kelvin approx\nstars  (core ) even hotter !!

The sun is about 15 million degrees C. at its core and about 11000 degrees C. on its surface. Way too hot for anyone to get anywhere close to it.

They can basically find out the composition of the sun ie.., what material it is made up of, which is because different elements have unique spectral characteristics.And they can estimate its surface temperature.

Aside from the obvious size difference (109 times in diameter) the sun is made up of Hydrogen and helium, while the Earth has much heavier elements, the surface of the sun is as hot as the core of the earth, and is very, very bright.\n\nEarth                   \n\nVolume___________1.08 X 10^12 Km^3       \nSurface Area_____5.1 X 10^8   Km^2       \nMass_____________5.97 X10^24  Kg         \nGravity__________9.8 m/s^2\nSurface Temp.____-88-58 degrees C       \nCore Temp._______6226.85 degrees C\nChemical makeup__98% nitrogen and Oxygen (atmos.)         \n\nSun\n\nVolume___________1.41 X 10^18 Km^3\nSurface Area_____6.09 X 10^12 Km^2\nMass_____________1.98 X 10^30 Kg\nGravity__________273.95 m/s^2\nSurface Temp.____5506 degrees C\nCore Temp._______4.99 X 10^6 C\nChemical Makeup__98% Hydrogen and Helium\n\nThe sun is 332,590 times more massive than Earth.
