Explain the difference between conductor and insulator
Convection is the transfer of heat in a liquid or gas due to the movement of molecules. The heated molecules move upwards and cooler molecules move downwards. This type of heat transfer is responsible for weather patterns, ocean currents, and more.
Convection: Heat Transfer Through Fluid Movement
Draw a convection current in a beaker. Label which parts are hot and cold.
Convection is the transfer of heat through the movement of a fluid or gas. The warmer fluid or gas rises while the cooler fluid or gas falls, creating a cycle of heat transfer.
Convection can occur without the presence of matter, as when an electric field is present in a plasma. Convection can occur in the Earth's atmosphere, which causes changes in weather patterns. The convection of heat can be used to power machines, such as engines.
