Discussion on Fire Characteristics of Dwellings with a Small
... But, why couldn't curtains or wood frames burn in spite of such an intensive heat radiative source, i.e., the burning room, and such a short distance, i.e., 3.3 meters? This is because there is a heavy loss in heat radiation. As we know, so long as the temperature of a body is higher than absolute z ...

It appears reasonable to expect that if thermal convection occurs in the Earth’s mantle, it may also occur within the Moon and Mars. The dimensions of these latter two bodies are comparable to the thickness of the Earth’s mantle. ...
