How does heating a coffee shop with a radiator relies on creating convection currents in the air of coffee such as beans? Explain in full depth with seven steps. (DIFFICULT)

1. Energy is transferred from the radiator to nearby air particles by conduction 2. The air particles collide with the radiator surface 3. The air by the radiator gets warmer and less dense (as air particles move quicker) 4. The warm air therefore rises and is replaced by the cooler air. The cooler air is then heated from the radiator 5. At the same time, the previous heated air transfers energy to the surrounding (e.g the walls and contents of the room). 6. It cools, becomes denser and sinks 7. The cycle repeats, causing a flow of air to circulate around the coffee shop - called a convection current
