Answer Posted / mohan
VERTICAL ONE WILL COOL FASTER DUE TO NATURAL CONVECTION OF
HOT AIR FROM THE SURFACE OF THE PLATES ON BOTH THE SIDES...
BUT IN CASE OF HORIZONTAL PLATE, DOWNWARD SURFACE EMITTING
HEAT,THE AIR WHICH GETS HEATED UP CANNOT RISE UP (HOT AIR IS
LIGHTER THAN COLD AIR) SO, THE HEAT DIFFERENCE BETWEEN THE
PLATE SURFACE AND AIR AT BOTTOM IS LESS COMPARED TO THE
VERTICAL CASE, HENCE VERTICAL PLATE WILL COOL FASTER....
