Expert Answer
Convection is used in the following cases:
Boiling water: When water starts getting heated, the water molecules expand and move in the spot. Thus heat is transferred to other parts od the pot and the cold water starts sinking whilw thw warm water rises.
Hot air baloon: The air inside the balloon is contibuously heated, which makes it warmer. Th warm air rises and the balloon too.
Land and sea breeze: The land near the sea is warmer in the afternoon than in the evening. this warm air rises by the principle of convection and is replaced by cooler air.Similarly during the night, the air near the sea is warmer than that at the shore. That's because the warm air rises and is replaced by cooler air.
