Lava is magma that is erupted onto Earth's surface. The temperature is essentially the same, except for the cooling that may occur after eruption.
Wikipedia gives the range of magma temperatures as normally between 700 C and 1300 C. Lava is magma that has been forced out into air or water.
Matt surfaces are better absorbers of thermal radiation than shiny surfaces, as the light "bounces" around on the Matt surface meaning more energy can be absorbed, compared to a shiny surface. A look at a cross section of a Matt surface may be helpful.
It's hotter today than it was yesterday. She's so much hotter with a tank on. It's gotten a lot hotter in here. Can we turn the air on?
No
The temperature of her body was hotter than a volcano.
It depends on what is burning. While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F.It would depend. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.
Lava (and any other material) will cool down if it is surronded by material that is at a lower temperature than itself and heat up if the surrounding material is hotter. By definition, lava is molten rock that has been erupted onto the earth's surface. As such it is surrounded by material that is at a much lower temperature than itself so will lose heat and so decrease in temperature.
Magma is hotter than lava because magma is located beneath the Earth's surface where it is exposed to higher temperatures and pressures compared to lava, which is magma that reaches the surface. As magma rises to the surface and cools, it loses some of its heat energy, resulting in the lower temperature of lava.
Yes, magma is hotter than fire. Magma is molten rock found beneath the Earth's surface, with temperatures reaching up to 1300-2400°F, while fire is a chemical reaction that emits heat and light, typically with temperatures up to around 1000-1800°F.
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
Yes. Lava is 700° to 1250° Celsius and the Sun is 5496.85 degrees Celsius.
yes because lava is exposed to the surface while magma is below Earth's suface which would be hotter than the suface
Yes. The sun is much hotter and even the hottest lava.
Volcanoes spew lava. Lava is molten rock. Molten rock is liquid.
The sun is much hotter than the Earth's crust. The temperature at the Earth's core is estimated to be around 5700 degrees Celsius, whereas the temperature at the surface of the sun is about 5500 degrees Celsius.
its just lava when it reaches earth's serface, its magma when its still inside Molten rock on the surface is called lava. It is cooler than magma, and quickly becomes solid. This is because it is much cooler on the earths surface than inside the earth. As magma rises it starts to cool, as you go up the volcano it gets cooler by 15 degrees every 1 km. so when the magma gets to the top of the volcano it is cooled down quite a bit and turns into lava
Lava on Earth's surface is exposed to air, which is of course much cooler than the lava. The air then carries heat away from the surface of the lava flow rather quickly. Since rock, molten or otherwise, is a poor conductor of heat the interior of the lava flow cools much more slowly and does not supply heat to the cooling outer layer. As a result the lava forms a thing solid crust. Until a thick insulating crust has built up the surface will remain quite hot, just not hot enough to be molten.
