So in the late 1700s, he conducted experiments involving red-hot iron balls. He noted that when the difference in temperature between the ball and the surrounding air was less than 50 degrees Fahrenheit (10 degrees Celsius), the rate of heat loss was proportional to the temperature difference...
Plate motion requires a hot mantle. And indeed, as you go deeper into the Earth, the temperature increases. At the bottom of the plates, around 60 miles (100 kilometers) deep, the temperature is about 2,400 degreesFahrenheit(1,300 degreesCelsius). By the time you ...
in geyser fields in such diverse locales as Iceland, New Zealand, Chile and the U.S. [source:Glennon]. The one thing all of these locations have in common with one another is a high level ofgeothermal activity, one of the key components of geyser formations.Geothermal energy, which is t...
However, volcanoes sometimes erupt in the middle of tectonic plates. The sources of these hotspots might be mantle plumes, mushroom-shaped pillars of hot rock ascending from the deep mantle to sear overlying material like a blowtorch. As tectonic plates wander over such plumes, geologists think ...
One of the many rewarding experiences of drinking tea is the savouring of the flavours in each sip. The true appreciation of the depths of flavour in a tea and how it begins, how it develops and then how it lingers afterwards is a never ending learning e
However, the park has a huge, terrifying secret: It's an active supervolcano and one of the largest volcanic systems in the world. Yellowstone sits above a spot in the Earth's mantle where columns of hot, molten rock called plumes rise to form volcanoes in the planet's crust. This spot...
How hot is jet engine exhaust? Jet engine exhaust isbetween 600 and 1,500 degrees Celsius in temperature. This high heat is as a consequence of kerosene burning in the presence of oxygen. Kerosene is a hydrocarbon mixture and hydrocarbons react very exothermically with oxygen. ...
