what is the approximate temperature of molten lava?
539186
Approximately 2000 degrees F unless it is in a Lava tube, then it can be over 3000 degrees F because the heat is contained.\n\nThis also allows the lava to stay in a liquid state and travel farther as seen in Hawaii where it travels underground exiting into the ocean.

temperature of fire was 900°F to 1200°F\n\nMost volatiles ignite at temperatures ranging from 1000º - 1400º F.\n\ncombusted in the fourth and final state at temperatures in excess of 935°F.

If it touched a vital part of your body, yes.  Certainly it would burn and the least that it would do is burn off the part that touched it.\nHow hot is lava?\nLava is extremely hot. Lava can reach temperatures of about 1,250° Celsius. The lava of the Hawaiian volcanoes reach these temperatures. Normal lava temperatures reach 750° Celsius. That is still much hotter than your oven is capable of reaching. \nWhy does the lava get so hot?\nIt is very difficult to melt rocks, because they are so strong. The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt. Once that happens, the magma (molten rock) will rise toward the surface (it floats). Deeper inside the earth, the temperatures are so hot that the entire outer core is molten. The inner core is made of different chemicals, so they are not molten.

mafic magma - about 1100 Celcius\nintermediate magma - about 1000 Celcius\nfelsic magma - about 800 Celcius

The temperature where the substance turns from a solid to a liquid. The melting temperature of ice is 31.9999 degrees Fahrenheit.\n\nThe melting point for gold would be much higher as it must be very hot for gold to turn to a liquid.

when a volano explodes it erupts lava.The lava is very hot but it still cant melt the volcano.The lava will cool off,forming a rock.Rocks that are formed when lava cools is called a Igneuse rock.It is very hard to melt a intire volcano.If the lava melts the volcano at all,only a little bit of the inside would be melted. the lava just dries up

1) Calculate the heat needed to melt 100 grams of ice completely: \nMass of ice * Heat of Fusion\n100g * 333J/g = 33300 J\n\n2) Calculate the cooling we can obtain \nMass of water * specific heat of water * temperature loss\n180g * 4.2 J/g K * dT = 33300 J => dT = 44.0 degrees\n\nConclusion we need only to melt 100g * 30/44 = 68.1 gram of ice to cool down the water to zero degree. 31.9 grams of ice remains.\n\n3) 1) Calculate the heat needed to melt 50 grams of ice completely: \nMass of ice * Heat of Fusion\n50g * 333J/g = 16650 J\n\n4) Calculate the cooling we can obtain \nMass of water * specific heat of water * temperature loss\n180g * 4.2 J/g K * dT = 16650 J => dT = 22.0 degrees\n\n5) Calculate the average temperature of the water.\nAfter melting of the ice we have 50 g of water at 0C and 180 g of water at 30-22=8C. This average out to 6.3C

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*

Hey this is an outstanding question because it really gets into the difference between temperature and heat and the power of the sun. All important stuff.\n\nThe answer is it depends on the time of day, the day   of the year, the diameter of the magnifying glass, and what you are heating!\n\nBooooring warning: The spot of light from even a small sized magnifier if reflected off white paper or a shiny surface can actually damage your vision. Be careful out there!\n\nSolar ovens can reach 400 F, enough to cook with.\n\nSolar forges can get up to temperatures which can melt metal.\n\nTemperature just measures how fast the molecules and atoms in stuff are jiggling or zooming around. \n\nHeat is a measure of energy, and for a particular piece of stuff, it is often related to temperature almost proportionally, like you double the temperature of a cup of coffee from 68 F to 136 F and the heat (energy) in the water roughly doubles too!\n\nThings can be wicked high temperature, but have very little heat. For instance at high altitudes the atmosphere is almost a vacuum and the molecules go whizzing around. The temperature is insanely high, but jet airplanes don't melt. Because there is so little matter.\n\nOr an object can have lots of heat but not burn you. Check out the science demo in the sources about holding a glowing red space shuttle tile in your bare hand.

Like all elements, its physical state depends on temperature and pressure. It is a liquid at room temperature, but can be frozen and evaporated at extreems.\n\nIt freezes at -38.83 °C, -37.89 °F\nIt boils at 356.73 °C, 674.11 °F

Some are formulated to melt at lower temps some as low as 95 deg F. Some for use making candles and for food use melt between 170 and 200 deg.F. Their is no such thing as liquid parafin in a bottle no mater what it is labled. The waxes with a lower melting point are just a little more refined or have highly refined additives such as fregrent oils or light hydrocarbons

Mafic lava is very hot and flows easily it contains less silica and are enriched in iron (Fe), magnesium (Mg), and calcium (Ca) and just encase your trying to get a homework answer I will leave it at that if not you will know what I mean ;)
