The release of heat from the cooling of the mass takes place throughconductivity, or by moving (convectoin), or byboth. In solids it is solelyby conduction, in liquid and gas the main role is playedmoving or mixing (convection) through circulating currentsconstantly move the hot and cold parts. The larger the sizenot yet condensed spheroids, gaseous or of liquid droplet, ormixed, the more is the obstacle to cooling due to the greaterthe distance which must pass circulating currents. Of course, thiscomplex: the speed of currents varies. Nevertheless, it is clear that in the ball,whose diameter is 11 times more the moving material from the center tothe surface and back from the surface to the center will require much moretime, though the movement has not experienced delays. But in thosethe cases that we are considering, is severely delayed. In a rotatingaround its axis the spheroid exert a force to slow it andgrowing with the speed of rotation. In such a spheroid the different parts of substances(assuming the same angular speed in its rotation around its axis, towhat they will more and more seek as seals) mustto vary the absolute speed depending on their distance fromaxis, and circulating currents must constantly change the distanceresulting necessarily or decreases or increases the numbermotion in each particle. When passing through each of liquid droplet environmentparticle due to the friction loses power, then increasing his movement, theslowing it down. Here is that, when the larger spheroid has alsogreater speed of rotation, the relative slowness of the circulating currents andthe consequent slow cooling should be much more than thosewhat can be expected as a consequence of the incremental distance, which shouldto be completed with each part.
