Here's a breakdown:
* Convection is a type of heat transfer that occurs in fluids (liquids and gases).
* Density difference: When a fluid is heated, the warmer parts become less dense and rise, while the cooler, denser parts sink. This creates a cycle of movement.
* Pressure difference: The rising and sinking of the fluid creates pressure differences, which drive the flow.
Examples of convection:
* Boiling water: As water heats up at the bottom of a pot, the hot water rises, while the cooler water sinks, creating a convection current.
* Weather patterns: Warm air rises and cools, creating convection currents that drive weather systems.
* Heating a room: A radiator heats the air near it, causing the warm air to rise and circulate, creating a convection current.
