Anywhere in between. The farther open valve is the warmer radiator will get during normal operation of heat system.
Conduction of heat energy from the source to the water in the boiler. A pump moves the hot water to the radiator.The heat radiates out from the radiator to the air, where convection then circulates it through the room.

If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler
The boiler has a circulation pump that circulate the water
Not for the faint of heart! For a Combi/Evaporation boiler: Switch off the boiler. Take a reading of the boiler water pressure gauge. Shut off the radiator's thermostat valve(if fitted)/supply valve and return valves, connect a hose to the drain and put the other end into a large container below the level of the bottom of the radiator. Open the draincock first and then the air bleed valve and let the radiator drain. Close the draincock. When refilling the radiator put the anti-corrosion treatment in first then open the thermostat valve and return valve as wide as possible. when the air is expelled, close the air bleed screw. Using the fill loop restore boiler pressure. Put all thermostat valves(if fitted) to max and fire up the boiler. After the boiler has run for 10 minutes, switch off, or so go to the highest radiator and bleed out the air. WARNING: the water/steam will be very hot and likely to spit. Use a cloth as a barrier and to mop up any spills. Recheck the boiler pressure and top up as necessary.

think of a circuit with a cell , wires and a bulb. now think about a boiler and pump, pipes and a radiator. the cell is like the boiler and pump because it has the energy. the pipes are like the wires because they transfer the energy. the bulb is like the radiator because they use the energy changing it into light energy and heat energy when referring to them especially.
on hot water heat with a boiler you should pressurize the system then open the bleeders
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
The Cornish Boiler only has one fire tube compared to the Lancashire Boiler's two.

Depends on how many sections of the radiator and the height and width
